Wikis read-only: Datacenter switchover
Completed - The scheduled maintenance has been completed.
Oct 28, 15:10 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Oct 28, 15:00 UTC
Scheduled - The SRE team will run a planned data center switchover, moving all wikis from our data center in Virginia to the data center in Teaxs. This is an important periodic test of our tools and procedures, to ensure the wikis will continue to be available even in the event of major technical issues.

The switchover process requires a brief read-only period for all Foundation-hosted wikis, which will start at 15:00 UTC on Wednesday October 28th and will last for a few minutes while we execute the migration as efficiently as possible. All our public and private wikis will be continuously available for reading as usual, but no one will be able to save edits during the process.
