GitHub’s blog frequently features extensive reports about its outages — exactly what happened, how they put out the fire, and what measures they put in place so the situation can’t happen again. Besides being a textbook example of crisis communication, they’re an enormous well of know-how for sysadmins and DevOps.

As always, we strive to provide detailed, transparent post-mortems about these incidents. We’ll do our best to explain what happened and how we’ve mitigated the problems to prevent the cause of this outage from occurring again.
