We hope you'll never see this message...
...but things fail all the time. It's how you respond that makes the difference. Get quick and contextful alerts on any channel you want. Know when your service fails before your customers do.
How it works
Set up your thresholds
The internet can be flaky. Sometimes a failing service is just fine 2 seconds later. Dodge false positives by specifying exactly when you should alerted and how often you want to be reminded.
We don’t put any limits on the amount of email, Slack, Pagerduty or webhooks alerts you can send.
We check your domain’s SSL certificates for expiry and follow the exact same alerting patterns as all the other checks.
By default, we retry any failing check from another data center location, just to be sure.
