Reliability Guarantees

The service is currently run on Hetzner bare metal servers. The app servers are load balanced, but the Postgres database currently is a single point of failure. The database does have daily backups. The ops team consists of a single person, so multi-hour or even multi-day outages are possible!

While we can only guarantee a best effort availability, in practice the availability has exceeded 99.9% since the service publicly launched in July 2015. That is, until 20 August 2016, when the service experienced a 24 hour outage.

There's also a number of alternative cron monitoring services, with different feature sets, different reliability guarantees and pricing options. If doesn't seem like a good fit for you, why not check them out:, Dead Man's Snitch, Coal Mine, PushMon,, CronAlarm, Watchdog Timer.
