Your SSL certificate expires in 7 days.Would you know?

What we watch

Four ways your site breaks silently

The failures that take sites down rarely announce themselves. These four do their damage quietly - so the watch is built around them.

• Certificates

  SSL expiry, caught early

  We open a real TLS connection, read the certificate that's actually being served, and warn you 30, 14, 7, 3 and 1 days out - plus the moment one goes self-signed, mismatched or invalid.

• Domains

  Domains that never lapse

  Auto-renew failing silently is how good domains die. We track registration expiry over RDAP, with a WHOIS fallback, so a dead card on file never takes your site down.

• DNS

  DNS changes you didn't make

  A flipped A record or a hijacked nameserver is an incident. We snapshot A, AAAA, MX, NS, CNAME and TXT daily and alert only on changes confirmed twice - so propagation noise never pages you.

• Uptime

  Uptime, without the false alarms

  Checks from North America, Europe and Asia. You're paged only when two regions agree the site is down across two consecutive checks - never from a single 3am network blip.

The full watch

Everything else it keeps an eye on

The four silent failures are the core. Around them, the things teams actually need to run monitoring in production.
