Don't just check uptime once — watch it 24/7

This is a one-time check. Turn on monitoring and we'll watch the domains that matter to you continuously, notifying you the moment anything moves across all three signals:

Uptime monitor with 7-day uptime percentage, failed checks, average latency by region, and daily outages

Uptime

We visit the site from multiple regions worldwide and email you within minutes if it goes down, with a per-region breakdown so a real outage stands out from a regional blip.

DNS changes

We watch NS, MX, CAA, CNAME, TXT and A/AAAA records, and identify the host, network, and ASN behind them, so a real migration or hijack stands out from routine noise.

TLS certificate

We warn you 30, 14, 7, and 1 days before it expires, and flag it if the issuing authority changes or the certificate is unexpectedly replaced.

Monitor uptime free

Free for your first domain: uptime, DNS, and certificate together. No credit card.

About Website Uptime Monitoring

This page shows whether we could reach a website the last time we checked it. We also keep a record of when it went down and came back, so you can see whether an outage is new or has happened before. For each site we show:

  • Website availability and response status
  • Server software and configuration
  • Meta information including titles and descriptions
  • Historical uptime patterns

What this page reports

  • Last status change: When we last saw a site switch between reachable and unreachable
  • Last downtime: When a site was most recently seen down, and whether it has come back
  • Server and meta information: The server software, page title and meta tags we last observed

We check a domain at most once a day and record an observation only when something changes, so these are the times a change was seen rather than the exact moment it happened. For continuous, minute-by-minute checks with alerting, use website monitoring.
