Check activity — last 7 days
The 50 domains most frequently audited on CheckFast over the last seven days. Check volume is a real-time signal of what developers and site owners are actively investigating — a spike often correlates with a deployment, incident or SEO push.
Check volume is a leading indicator of technical activity. When a domain spikes to the top of this list it usually means something changed — a new deployment triggered an SSL warning, a DNS migration is under way, an SEO audit was kicked off, or a developer is diagnosing an email deliverability issue before a campaign goes out. The trending list is a real-time window into the kinds of problems the developer community is actively debugging.
For infrastructure and security teams this list has a second use: it surfaces domains that are being checked frequently by multiple people, which can be an early indicator of public discussion around an outage or misconfiguration. If a well-known domain is trending heavily, it is worth clicking through to see whether a specific check dimension is returning failures.
Each row links to the full per-domain health report at /check/{domain}, which aggregates the most recent public check result per tool into a single view. Where persisted scores are available they are shown; where a tool has not yet been run, the report provides a one-click live check.
The window resets every seven days and revalidates every hour. Domains that were trending last week but have not been checked since will age out and make room for newly active domains. If you want your domain to stay visible here, keep running public checks — each one is counted.
