Every site has an Alerts panel with three steps. Sites without their own settings follow Default alerts for all sites under Settings → Alerts.
1. Where should alerts go?
Tick channels. Your own e-mail is always there; type an address to add a colleague, or add Slack, SMS or a webhook as a channel.
2. When should we contact you?
On an outage, when the site is back, on slow responses, and well before something expires. Outages are always confirmed from a second location first.
3. If nobody takes care of the alert (optional)
Every alert and the site page has an On it button. Pressing it tells your colleagues someone is handling it. You never have to press it – but if you turn on this step, it is how we know to stop: if nobody has pressed it within N minutes, also alert these channels, and remind every M minutes until someone does. Leave the step off and you get one alert per outage.
Snooze
On the site page you can also snooze an incident for 30 minutes to 24 hours – reminders pause, the incident stays open.
