We launched the new Basecamp on March 6. Since then we’ve deployed 891 new versions with all sorts of new features, bug fixes, and tweaks. Through all of that we’ve had just six incidents of either scheduled or unscheduled downtime for a total of 19 minutes offline.

Today, that means we’ve been available 99.99% of the time since launch. That’s worth celebrating! Our fantastic operations teams consisting of Anton, Eron, John, Matt, Will, and Taylor have worked tirelessly to eliminate interruptions and they deserve our applaud.

Since we count “scheduled” downtime the same as “unscheduled” (have you ever met a customer who cared about the difference?), that has meant making good progress on stuff like database migrations.

In the past, when we focused mainly on unscheduled downtime as a measure of success, we wouldn’t think too much of taking a 30-minute window to push a major new feature. Not so these days. Thanks to Percona’s pt-online-schema-change, we’re able to migrate the database much easier without any downtime or master-slave swappero.

So three cheers to the four 9’s! Our next target is five 9’s, but that only allows for 5 minutes of downtime in a whole year, so we have our work cut out for us.
