Uptime and alerting

Monitoring

Know your website is down before your customers do.

What it does

Checks uptime, SSL certificates, domain expiry, DNS records and email authentication, on the interval your plan allows.
A failure is confirmed before anybody is woken: a monitor has to fail a set number of checks in a row before an alert is sent.
Alerts reach a distribution list rather than one person, and can escalate to a second list after a number of minutes if nobody has acted.
Quiet hours are kept in your own timezone, so overnight alerts hold until morning without anyone changing a clock.
Alerts can also go to Slack, Teams or any webhook, and by SMS.
Scheduled maintenance windows suppress alerts without stopping the checks, so a planned deploy does not page anyone while the history stays honest.

Monitoring is one of fifteen services on one account, one bill and one set of people. See them all, or compare the bundles.
