A site goes down, an <a href=\"https:\/\/www.dchost.com\/ssl\">SSL certificate<\/a> quietly expires, or a critical domain slips past its renewal date, and suddenly your team is firefighting instead of building campaigns. The solution is not another spreadsheet, but a monitoring and alert architecture that treats uptime, SSL expiry and domain renewal as one integrated system. In this article, we will walk through how we design this stack for agencies at dchost.com, from data model and tooling choices to practical alert rules and workflows your team can actually maintain.<\/p>\n<p>We will focus on three pillars: external uptime monitoring so you know when a site is unavailable; SSL certificate monitoring so you never ship a \u201cNot Secure\u201d browser warning; and domain renewal monitoring so you do not lose hard-won domains. Along the way, we will show how to plug this into the hosting and DNS infrastructure you already use and how to grow from a handful of sites to hundreds without adding operational chaos.<\/p>\n<div id=\"toc_container\" class=\"toc_transparent no_bullets\"><p class=\"toc_title\">\u0130&ccedil;indekiler<\/p><ul class=\"toc_list\"><li><a href=\"#Why_Agencies_Need_a_Unified_Monitoring_Architecture\"><span class=\"toc_number toc_depth_1\">1<\/span> Why Agencies Need a Unified Monitoring Architecture<\/a><\/li><li><a href=\"#Step_1_Build_a_Clean_Inventory_of_Client_Websites\"><span class=\"toc_number toc_depth_1\">2<\/span> Step 1: Build a Clean Inventory of Client Websites<\/a><\/li><li><a href=\"#Step_2_Uptime_Monitoring_That_Scales_Beyond_a_Handful_of_Sites\"><span class=\"toc_number toc_depth_1\">3<\/span> Step 2: Uptime Monitoring That Scales Beyond a Handful of Sites<\/a><ul><li><a href=\"#What_to_Monitor_for_Uptime\"><span class=\"toc_number toc_depth_2\">3.1<\/span> What to Monitor for Uptime<\/a><\/li><li><a href=\"#Where_to_Run_Uptime_Checks_From\"><span class=\"toc_number toc_depth_2\">3.2<\/span> Where to Run Uptime Checks From<\/a><\/li><li><a href=\"#How_Often_to_Check_and_When_to_Alert\"><span class=\"toc_number toc_depth_2\">3.3<\/span> How Often to Check and When to Alert<\/a><\/li><\/ul><\/li><li><a href=\"#Step_3_SSL_Certificate_Expiry_Monitoring_That_Actually_Works\"><span class=\"toc_number toc_depth_1\">4<\/span> Step 3: SSL Certificate Expiry Monitoring That Actually Works<\/a><ul><li><a href=\"#Discovering_All_SSL_Endpoints\"><span class=\"toc_number toc_depth_2\">4.1<\/span> Discovering All SSL Endpoints<\/a><\/li><li><a href=\"#Alert_Thresholds_and_Ownership\"><span class=\"toc_number toc_depth_2\">4.2<\/span> Alert Thresholds and Ownership<\/a><\/li><\/ul><\/li><li><a href=\"#Step_4_Domain_Renewal_Monitoring_and_Portfolio_Hygiene\"><span class=\"toc_number toc_depth_1\">5<\/span> Step 4: Domain Renewal Monitoring and Portfolio Hygiene<\/a><ul><li><a href=\"#Single_Source_of_Truth_for_Domains\"><span class=\"toc_number toc_depth_2\">5.1<\/span> Single Source of Truth for Domains<\/a><\/li><li><a href=\"#Alert_Windows_and_Billing_Workflows\"><span class=\"toc_number toc_depth_2\">5.2<\/span> Alert Windows and Billing Workflows<\/a><\/li><\/ul><\/li><li><a href=\"#Step_5_Alert_Routing_Noise_Reduction_and_Runbooks\"><span class=\"toc_number toc_depth_1\">6<\/span> Step 5: Alert Routing, Noise Reduction and Runbooks<\/a><ul><li><a href=\"#Designing_Alert_Channels_and_Escalation_Paths\"><span class=\"toc_number toc_depth_2\">6.1<\/span> Designing Alert Channels and Escalation Paths<\/a><\/li><li><a href=\"#Reducing_Alert_Fatigue\"><span class=\"toc_number toc_depth_2\">6.2<\/span> Reducing Alert Fatigue<\/a><\/li><\/ul><\/li><li><a href=\"#Step_6_Putting_It_All_Together_A_Practical_Architecture\"><span class=\"toc_number toc_depth_1\">7<\/span> Step 6: Putting It All Together \u2013 A Practical Architecture<\/a><ul><li><a href=\"#Core_Components\"><span class=\"toc_number toc_depth_2\">7.1<\/span> Core Components<\/a><\/li><li><a href=\"#Hosting_This_Architecture\"><span class=\"toc_number toc_depth_2\">7.2<\/span> Hosting This Architecture<\/a><\/li><\/ul><\/li><li><a href=\"#Operational_Best_Practices_and_Continuous_Improvement\"><span class=\"toc_number toc_depth_1\">8<\/span> Operational Best Practices and Continuous Improvement<\/a><ul><li><a href=\"#Make_Monitoring_Part_of_Onboarding_and_Offboarding\"><span class=\"toc_number toc_depth_2\">8.1<\/span> Make Monitoring Part of Onboarding and Offboarding<\/a><\/li><li><a href=\"#Test_Alerts_and_Runbooks_Regularly\"><span class=\"toc_number toc_depth_2\">8.2<\/span> Test Alerts and Runbooks Regularly<\/a><\/li><li><a href=\"#Use_Monitoring_Data_to_Improve_Hosting_Choices\"><span class=\"toc_number toc_depth_2\">8.3<\/span> Use Monitoring Data to Improve Hosting Choices<\/a><\/li><\/ul><\/li><li><a href=\"#Conclusion_Turn_Monitoring_into_a_ValueAdded_Service_Not_a_Burden\"><span class=\"toc_number toc_depth_1\">9<\/span> Conclusion: Turn Monitoring into a Value\u2011Added Service, Not a Burden<\/a><\/li><\/ul><\/div>\n<h2><span id=\"Why_Agencies_Need_a_Unified_Monitoring_Architecture\">Why Agencies Need a Unified Monitoring Architecture<\/span><\/h2>\n<p>Many agencies start with a patchwork: one vendor for uptime, another for SSL alerts, and registrar emails for domain renewals. It works until it does not. The real problems appear at scale:<\/p>\n<ul>\n<li>Different tools have different contact lists, so alerts miss the right person.<\/li>\n<li>Clients move between plans or hosting, but the monitoring configuration is not updated.<\/li>\n<li>SSL automation is set up on some servers but not others, so expiry risk is uneven.<\/li>\n<li>Domain renewal emails go to a former employee or the client instead of your operations team.<\/li>\n<\/ul>\n<p>A unified monitoring architecture solves this by treating each <strong>website<\/strong> as a single object with related checks:<\/p>\n<ul>\n<li>One or more URLs for uptime checks.<\/li>\n<li>One or more hostnames for SSL checks.<\/li>\n<li>One or more domains with registrar and expiry details.<\/li>\n<li>Contact and escalation rules owned by the agency, not scattered across vendors.<\/li>\n<\/ul>\n<p>This is the mindset behind our own internal tooling and the way we advise agencies who host on dchost.com <a href=\"https:\/\/www.dchost.com\/vps\">VPS<\/a>, <a href=\"https:\/\/www.dchost.com\/dedicated-server\">dedicated server<\/a>s, reseller hosting or colocation. Instead of three separate systems, think of a single monitoring inventory that other services feed from.<\/p>\n<h2><span id=\"Step_1_Build_a_Clean_Inventory_of_Client_Websites\">Step 1: Build a Clean Inventory of Client Websites<\/span><\/h2>\n<p>Everything starts with a reliable inventory. If you do not know exactly which domains and URLs you are responsible for, no monitoring tool can save you. For each client website, capture at least the following fields in a central system (it can be a database, a small internal app, or even a well-structured spreadsheet stored in Git):<\/p>\n<ul>\n<li><strong>Client name and billing ID<\/strong> \u2013 so you can tie alerts back to contracts.<\/li>\n<li><strong>Primary site URL<\/strong> \u2013 the canonical address used for uptime checks (for example, https:\/\/www.example.com).<\/li>\n<li><strong>Additional URLs<\/strong> \u2013 admin areas, APIs, staging environments if they need uptime checks.<\/li>\n<li><strong>Domain name(s)<\/strong> \u2013 including ccTLDs, defensive parked domains, and redirects.<\/li>\n<li><strong>Registrar and renewal date<\/strong> \u2013 whether it is at dchost.com or another registrar.<\/li>\n<li><strong>Hosting type<\/strong> \u2013 shared, reseller, VPS, dedicated, or colocation, and which provider.<\/li>\n<li><strong>SSL type<\/strong> \u2013 Let\u2019s Encrypt \/ ACME automation, commercial DV\/OV\/EV, wildcard or SAN.<\/li>\n<li><strong>Business criticality<\/strong> \u2013 low\/medium\/high helps prioritize alerts and uptime SLAs.<\/li>\n<li><strong>Alert routing<\/strong> \u2013 who is paged first, preferred channel, and escalation path.<\/li>\n<\/ul>\n<p>If you are just building this inventory, it is a good moment to run a technical review of each site. Our article <a href=\"https:\/\/www.dchost.com\/blog\/en\/ajanslar-icin-yeni-musteri-hosting-ve-dns-altyapisi-kontrol-listesi\/\">\u201cHosting and DNS Audit Checklist for Agencies When Onboarding New Clients\u201d<\/a> is a practical guide you can reuse as an intake form whenever a new project arrives.<\/p>\n<p>Once you have a clean inventory, design a simple unique ID for each <em>monitored component<\/em>: web endpoint, domain, SSL hostname. Your monitoring jobs will use these IDs to store results and your alert engine will use them to map events back to clients and contacts.<\/p>\n<h2><span id=\"Step_2_Uptime_Monitoring_That_Scales_Beyond_a_Handful_of_Sites\">Step 2: Uptime Monitoring That Scales Beyond a Handful of Sites<\/span><\/h2>\n<h3><span id=\"What_to_Monitor_for_Uptime\">What to Monitor for Uptime<\/span><\/h3>\n<p>For an agency, uptime monitoring is not just \u201cis port 80 open?\u201d It should answer:<\/p>\n<ul>\n<li>Is the public site reachable from the internet (DNS, network, HTTP status)?<\/li>\n<li>Is it serving the expected content and not just a generic error page?<\/li>\n<li>Is performance within normal bounds so users are not effectively seeing timeouts?<\/li>\n<\/ul>\n<p>Here is a simple layering you can apply:<\/p>\n<ol>\n<li><strong>HTTP status check<\/strong> \u2013 treat 2xx and 3xx as OK (with some nuance for SEO redirects), alert on 4xx\/5xx.<\/li>\n<li><strong>Content check<\/strong> \u2013 look for a stable keyword or HTML snippet, for example, the site tagline or footer brand.<\/li>\n<li><strong>Response time threshold<\/strong> \u2013 for high-value e\u2011commerce, alert if TTFB or full load exceeds your SLA (for example, 1\u20132 seconds).<\/li>\n<\/ol>\n<p>You can absolutely start with basic checks and refine over time. Our separate guide <a href=\"https:\/\/www.dchost.com\/blog\/en\/web-sitesi-uptime-izleme-ve-alarm-kurma-rehberi\/\">\u201cWebsite Uptime Monitoring and Alerting Guide for Small Businesses\u201d<\/a> explains baseline practices that apply equally well when you scale this for agencies.<\/p>\n<h3><span id=\"Where_to_Run_Uptime_Checks_From\">Where to Run Uptime Checks From<\/span><\/h3>\n<p>For agencies hosting many sites on dchost.com shared hosting, VPS or dedicated servers, we recommend a mix of:<\/p>\n<ul>\n<li><strong>External monitoring<\/strong> \u2013 probes from independent locations on the internet. This catches connectivity issues, DNS mistakes and routing problems that on\u2011server checks might miss.<\/li>\n<li><strong>Internal monitoring<\/strong> \u2013 lightweight HTTP checks from inside the same data center or even the same server, to catch PHP, database or local firewall problems earlier and with more detail.<\/li>\n<\/ul>\n<p>Open\u2011source tools (for example, Uptime Kuma, Prometheus + blackbox exporters, or custom scripts) work well when deployed on a management VPS or a dedicated server. For many agencies, it is efficient to dedicate a small dchost.com VPS as a \u201cmonitoring hub\u201d that runs periodic checks against all client sites, stores results, and exposes a small dashboard.<\/p>\n<h3><span id=\"How_Often_to_Check_and_When_to_Alert\">How Often to Check and When to Alert<\/span><\/h3>\n<p>Check intervals are a trade\u2011off between visibility, false positives and load:<\/p>\n<ul>\n<li><strong>Business\u2011critical sites<\/strong> \u2013 30\u201360 second intervals.<\/li>\n<li>Standard marketing sites \u2013 1\u20135 minute intervals.<\/li>\n<li>Low priority or rarely updated microsites \u2013 5\u201310 minutes.<\/li>\n<\/ul>\n<p>To avoid noise, use <strong>multi\u2011step alerting<\/strong>:<\/p>\n<ul>\n<li>Require 2\u20133 consecutive failures before sending the first alert.<\/li>\n<li>Retry from a second region before escalating.<\/li>\n<li>Automatically resolve the alert only after several consecutive successful checks.<\/li>\n<\/ul>\n<p>Also, encode <strong>maintenance windows<\/strong> in your monitoring. When you deploy a new version of a client WordPress or Laravel site on a dchost.com VPS, planned maintenance should not flood your channels. You can schedule maintenance windows in your monitoring tool or via tags on the inventory level.<\/p>\n<h2><span id=\"Step_3_SSL_Certificate_Expiry_Monitoring_That_Actually_Works\">Step 3: SSL Certificate Expiry Monitoring That Actually Works<\/span><\/h2>\n<p>Nothing undermines trust faster than a browser showing a big red \u201cYour connection is not private\u201d warning. SSL certificates have limited lifetimes; modern best practice is 90 days for ACME\u2011based automation. Agencies need a system that guarantees:<\/p>\n<ul>\n<li>You know <strong>every hostname<\/strong> that serves HTTPS for each client.<\/li>\n<li>You detect certificates that are not renewed by automation (for example, a plugin was disabled or ACME challenges started failing).<\/li>\n<li>You can act weeks before expiry, not hours.<\/li>\n<\/ul>\n<p>We wrote an in\u2011depth guide on this topic, <a href=\"https:\/\/www.dchost.com\/blog\/en\/onlarca-alan-adi-icin-ssl-sertifika-sure-sonu-izleme-ve-otomatik-yenileme-stratejisi\/\">\u201cMonitoring SSL Certificate Expiry Across Many Domains: Automation That Actually Scales\u201d<\/a>, which you can treat as the SSL\u2011specific companion to this article. Here, we will focus on how to plug SSL into your agency monitoring architecture.<\/p>\n<h3><span id=\"Discovering_All_SSL_Endpoints\">Discovering All SSL Endpoints<\/span><\/h3>\n<p>Start by mapping your domains to hostnames:<\/p>\n<ul>\n<li>Main sites: example.com, www.example.com<\/li>\n<li>Admin\/staging: admin.example.com, staging.example.com<\/li>\n<li>APIs: api.example.com<\/li>\n<\/ul>\n<p>For each hostname, record:<\/p>\n<ul>\n<li>The <strong>origin server<\/strong> (direct, or behind a CDN or reverse proxy).<\/li>\n<li>The <strong>certificate type<\/strong> (Let\u2019s Encrypt DV, commercial DV\/OV\/EV, wildcard, SAN).<\/li>\n<li>Who <strong>owns the renewal process<\/strong> \u2013 your team, the client, or a third\u2011party vendor.<\/li>\n<\/ul>\n<p>Then, automate certificate scanning. A simple TLS connection to each hostname can read:<\/p>\n<ul>\n<li>Issuer and subject.<\/li>\n<li>Valid\u2011from and valid\u2011until dates.<\/li>\n<li>SAN list to ensure all expected hostnames are covered.<\/li>\n<\/ul>\n<p>Store these in your monitoring database daily. Track both <strong>days until expiry<\/strong> and whether the issuer matches your expectations (for example, if a certificate suddenly switches from your trusted CA to an unknown one, that might signal a misconfiguration).<\/p>\n<h3><span id=\"Alert_Thresholds_and_Ownership\">Alert Thresholds and Ownership<\/span><\/h3>\n<p>For SSL alerts, we usually recommend three levels:<\/p>\n<ul>\n<li><strong>Info<\/strong> \u2013 30 days before expiry. Good for internal review, no need to wake anyone up.<\/li>\n<li><strong>Warning<\/strong> \u2013 14 days before expiry. Operations team should verify automation logs or schedule manual renewal.<\/li>\n<li><strong>Critical<\/strong> \u2013 7 days before expiry (or less, depending on risk). Escalate to on\u2011call or senior engineers.<\/li>\n<\/ul>\n<p>It is important that your monitoring system knows who owns each certificate. For sites hosted on your managed dchost.com infrastructure, your operations team might be responsible. For third\u2011party SaaS or customer\u2011hosted apps, the alert may need to be routed to the client\u2019s internal IT, with your account manager in copy.<\/p>\n<p>On dchost.com shared hosting, VPS and dedicated servers, ACME\u2011based automation (for example, Let\u2019s Encrypt) is the default choice. SSL expiry monitoring then becomes a <strong>safety net<\/strong>: you expect automation to handle renewals, and your alerts are there to catch edge cases before they become outages.<\/p>\n<h2><span id=\"Step_4_Domain_Renewal_Monitoring_and_Portfolio_Hygiene\">Step 4: Domain Renewal Monitoring and Portfolio Hygiene<\/span><\/h2>\n<p>Domain expiry is different from SSL expiry in one crucial way: if you miss an SSL renewal by a day, you have an outage; if you miss a domain renewal and it reaches redemption or deletion, you may <strong>lose the domain permanently<\/strong> or pay a hefty redemption fee. For agencies managing tens or hundreds of client domains, registrar email reminders are not enough.<\/p>\n<p>We highly recommend reading our article <a href=\"https:\/\/www.dchost.com\/blog\/en\/alan-adi-yenileme-grace-ve-redemption-sureleri-degerli-domainleri-kaybetmemek-icin-strateji-rehberi\/\">\u201cDomain Renewal, Grace Periods and Redemption Fees: How Not to Lose Your Best Domains\u201d<\/a> for a detailed breakdown of registry rules. Here, let us focus on the monitoring architecture.<\/p>\n<h3><span id=\"Single_Source_of_Truth_for_Domains\">Single Source of Truth for Domains<\/span><\/h3>\n<p>Just like websites, domains should live in a central inventory. For each domain, record:<\/p>\n<ul>\n<li>Registrar (for example, dchost.com or another provider).<\/li>\n<li>Expiry date and auto\u2011renew status.<\/li>\n<li>Who is billed and where invoices are sent.<\/li>\n<li>Technical contact and business owner at your agency.<\/li>\n<li>Whether the domain is <strong>critical<\/strong>, <strong>important<\/strong> or <strong>low value<\/strong>.<\/li>\n<\/ul>\n<p>From here, build an automated job that:<\/p>\n<ol>\n<li>Pulls expiry dates via registrar API where possible.<\/li>\n<li>Falls back to WHOIS queries when API access is not available.<\/li>\n<li>Normalizes the result and updates your inventory.<\/li>\n<\/ol>\n<p>WHOIS data is messy (GDPR redaction, different formats, rate limits), so prefer reliable APIs whenever you can. If your domains are primarily concentrated at dchost.com, consolidating scattered domains into a <strong>managed portfolio<\/strong> can significantly simplify both billing and monitoring.<\/p>\n<h3><span id=\"Alert_Windows_and_Billing_Workflows\">Alert Windows and Billing Workflows<\/span><\/h3>\n<p>Retrieve domain expiries once per day and trigger alerts based on risk:<\/p>\n<ul>\n<li><strong>90 days before expiry<\/strong> \u2013 internal reminder to check whether the domain is still needed and whether the client contract covers renewal.<\/li>\n<li><strong>60 days before<\/strong> \u2013 if you bill clients for renewals, send them a pre\u2011invoice or confirmation.<\/li>\n<li><strong>30 days before<\/strong> \u2013 operational reminder; verify that auto\u2011renew or manual renewal is arranged.<\/li>\n<li><strong>7\u201314 days before<\/strong> \u2013 critical alert if the domain is not yet renewed or confirmed.<\/li>\n<\/ul>\n<p>Combine this with a clear <strong>ownership policy<\/strong>: for strategic domains (brand, primary .com, main ccTLDs), the agency should strongly prefer to hold them in its own registrar account (with proper contracts and transparency) or at least have delegated management rights. For low\u2011value or campaign domains, you can accept more risk.<\/p>\n<p>If you maintain larger portfolios, our article <a href=\"https:\/\/www.dchost.com\/blog\/en\/alan-adi-portfoy-yonetimi-onlarca-domaini-kontrol-altina-alma-rehberi\/\">\u201cDomain Portfolio Management: Organizing Renewals, Billing and Brand Protection\u201d<\/a> goes deeper into tagging, cost centers and defensive registrations. The same structure aligns nicely with the monitoring strategy described here.<\/p>\n<h2><span id=\"Step_5_Alert_Routing_Noise_Reduction_and_Runbooks\">Step 5: Alert Routing, Noise Reduction and Runbooks<\/span><\/h2>\n<p>A good monitoring stack is as much about <strong>people and process<\/strong> as it is about tools. Agencies often fail not because they lack checks, but because alerts are noisy, unclear, or routed to the wrong person.<\/p>\n<h3><span id=\"Designing_Alert_Channels_and_Escalation_Paths\">Designing Alert Channels and Escalation Paths<\/span><\/h3>\n<p>For each client and each type of event (uptime, SSL, domain), decide:<\/p>\n<ul>\n<li>Primary channel \u2013 dedicated operations email, on\u2011call app, or a specific channel in your team chat.<\/li>\n<li>Secondary channel \u2013 escalation to a wider group or a manager if the issue is not acknowledged.<\/li>\n<li>Notification to client \u2013 for example, send a brief status update if downtime exceeds a certain threshold.<\/li>\n<\/ul>\n<p>Technically, this usually means your monitoring hub has a <strong>notification service<\/strong> that can send:<\/p>\n<ul>\n<li>Emails with clear subject lines, for example: \u201c[CRITICAL] Uptime \u2013 www.example.com \u2013 9 consecutive failures\u201d.<\/li>\n<li>Webhook calls into chat tools or ticketing systems.<\/li>\n<li>Optional SMS or voice calls for top\u2011tier SLAs.<\/li>\n<\/ul>\n<h3><span id=\"Reducing_Alert_Fatigue\">Reducing Alert Fatigue<\/span><\/h3>\n<p>To keep your team responsive instead of numb, introduce:<\/p>\n<ul>\n<li><strong>Grouping<\/strong> \u2013 if multiple checks fail for the same root cause (for example, a dchost.com VPS is down hosting 10 sites), send a single incident with a list of impacted sites.<\/li>\n<li><strong>Rate limiting<\/strong> \u2013 do not send more than one notification per X minutes for the same incident.<\/li>\n<li><strong>Auto\u2011resolution<\/strong> \u2013 send a clear \u201cRECOVERED\u201d message when things are back to normal.<\/li>\n<li><strong>Business hours vs 24\/7<\/strong> \u2013 some clients only pay for business\u2011hour support; alerts outside that window can be downgraded or batched.<\/li>\n<\/ul>\n<p>Most important, attach a <strong>runbook<\/strong> or troubleshooting link to each alert type. If an uptime alert fires, the notification should link to a shared document: steps to check DNS, hosting control panel, logs and common fixes.

By unifying uptime checks, SSL expiry monitoring and domain renewal alerts into one coherent architecture, you drastically reduce avoidable incidents while creating tangible value: higher availability, fewer \u201cNot Secure\u201d warnings, and no lost domains.<\/p>\n<p>The key is to think in layers: a clean inventory as the source of truth; automated uptime, SSL and domain checks feeding a central alert engine; and clear processes and runbooks so your team knows exactly what to do when something fires. With a small management VPS or dedicated server at dchost.com running your monitoring stack, and client sites hosted on properly sized reseller, VPS, dedicated or colocation infrastructure, you get a robust foundation that can grow with your portfolio.<\/p>\n<p>If you would like to redesign your hosting and monitoring approach for the next stage of your agency, our team at dchost.com can help you choose the right mix of hosting (from shared to VPS and dedicated) and design a monitoring hub that fits your tooling preferences. Start by auditing a handful of your most important client sites, then expand the same patterns across your full portfolio. Within a few weeks, you can move from reactive firefighting to proactive, measurable reliability your clients will notice.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>As soon as an agency passes 10\u201315 active client websites, manual checks and calendar reminders simply stop working.
