Downtime alerts

Downtime alerts where you already are

Alerts go where your team already looks, and only when a site is really down. One server outage sends one message, not one per site.

Downtime alerts

Every channel you use

Email, Slack, Discord, Telegram, Microsoft Teams, Google Chat, Mattermost, Rocket.Chat, PagerDuty, Opsgenie, Pushover, ntfy, SMS through your Twilio account, and webhooks with JSON.

Grouped and confirmed

A monitor is down only when every location fails twice in a row. Changes within a minute arrive as one message.

Pause and maintenance

Pause all alerts for an hour, a day or a week. Scheduled maintenance on your status page mutes them automatically.

History

Every alert sent, failed or skipped is listed with the reason, per monitor and per incident.

How it works

  2. Add your sitesPaste a list or import from your panel or DNS provider.
  3. RelaxWe check every minute and tell you the moment something is really down.

Questions

Will I get false alarms?

Rarely. A monitor is down only when every location fails two checks in a row, and Cloudflare challenges are shown as "challenged", not down.

Can alerts open PagerDuty incidents?

Yes. Each monitor that goes down opens an incident that resolves itself when it is back.
