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

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, DNSSEC, CNAME 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

Use the Who.is uptime information to track the availability and server information of websites. This helps track:

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

This information is valuable for website owners, system administrators, and anyone interested in monitoring website reliability and performance.

Metrics we monitor

  • Uptime percentage: The percentage of time your website is accessible
  • Response time: How quickly your server responds to requests
  • Status codes: HTTP response codes indicating server status
