Eighteen alert types, each with its own switch: droplets that go off or fill their disk, failed or unusually slow deploys, apps that are unhealthy, keep restarting or run hot, databases, uptime checks, Kubernetes clusters, load balancers, certificates, cloud firewalls, your account and your spend.
Alerts in the same minute share one notification. When DigitalOcean has an incident in your region, related alerts wait under one incident notification instead of buzzing one by one. Urgent ones repeat every 5 minutes, up to 3 times, until someone taps "I'm on it" in the notification, which quiets every device on the account. "Snooze 30 min" is there too, and you can mute one resource on every device or choose which resources can notify you.
Open an urgent alert from its notification and it stays on your Lock Screen and in the Dynamic Island until it recovers.
