We'll be performing security maintenance tomorrow, Saturday August 22nd from 9PM until 1AM on the 23rd (Pacific time), to implement recommended updates from our upstream software vendors. We expect the site to be unavailable for approximately 10-15 minutes during this window and will attempt to perform the updates sequentially around the cluster to minimize the impact.
If you need to track the progress or contact us during the work, you can follow our Twitter account as we post updates. If you have any questions, don't hesitate to contact us.
