As our infrastructure continues to grow and evolve, it’s sometimes necessary to perform system maintenance that may cause downtime. We have a number of projects queued up over the coming months to take our infrastructure to the next level, so we are announcing a scheduled maintenance window on Saturday mornings beginning at 0500 Pacific.
We do not intend to perform maintenance every Saturday, and even when we do, most of them will not be disruptive to customers. We are using these windows only in cases where the tasks we’re performing have a higher than normal level of risk of impacting the site.
We will always update our status site before we begin and again when we’re done. In cases where we expect there to be more than a few minutes of disruption we will also make an announcement on the GitHub Blog by the preceding Friday.
To get things started on the right foot, we will be performing an upgrade of the software on some of our network switches this Saturday during the new maintenance window. We do not expect this to cause any visible disruption.
