        <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 Google Cloud Platform.
            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
            for you, why not check them out:
