<h3>Open Source</h3>
|
|
<p>
|
|
healthchecks.io is an open source project. The code is on
|
|
<a href="https://github.com/healthchecks/healthchecks">GitHub</a>,
|
|
it has BSD license, and is accepting contributions.
|
|
</p>
|
|
|
|
<h3>Reliability Guarantees</h3>
|
|
<p>
|
|
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!
|
|
</p>
|
|
<p>
|
|
While we can only guarantee a <em>best effort</em> 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 <a href="https://medium.com/@healthchecks/outage-postmortem-20-august-2016-204297b9d3dd#.dahxkssp8">experienced a 24 hour outage</a>.
|
|
</p>
|
|
|
|
|
|
<p>
|
|
There's also a number of alternative cron monitoring services, with
|
|
different feature sets, different reliability guarantees and
|
|
pricing options. If healthchecks.io doesn't seem like a good fit
|
|
