Recently, we’ve had multiple service interruptions on GitHub.com. We know how important reliability of our service is for your projects and teams. We take this responsibility very seriously and apologize for these disruptions.
These incidents were distinct events, but have a common theme of uncovering new challenges in scaling our database tier. Specifically, increased load on our largest database cluster contributed to degradations across multiple services.
In the coming weeks, we’ll follow up with a more in-depth and technical report of these events and the work we are doing to improve the scalability and performance of our backend systems.
We have several data partitioning initiatives already in progress, and we’ll be rolling out some of this work very soon. You can follow our status page for updates about the availability of our systems.
