Hi,
The next datacenter switchover, going from codfw (Texas) to eqiad (Virginia), will be the week of Sept. 13. The schedule is as follows:
Services: Monday, Sept 13th 14:00 UTC Traffic: Monday, Sept 13th 15:00 UTC MediaWiki: Tuesday, Sept 14th 14:00 UTC
If you're not familiar with this process, see https://wikitech.wikimedia.org/wiki/Switch_Datacenter. We also recently published a blog post recapping the June switchover: https://techblog.wikimedia.org/2021/07/23/june-2021-data-center-switchover/.
https://phabricator.wikimedia.org/T287539 is the Phabricator tracking task for this switchover.
Thanks, -- Kunal
