Hello,
On June 29, all traffic from all wikis will be switched to the secondary data center (like we did in 2020). *All wikis will be in read-only mode on June 29 around 14:00 UTC*. A message to inform our communities has been written, to be sent to wikis: https://meta.wikimedia.org/wiki/Tech/Server_switch_2020
Please don't bother with the page title. We may move the page to [[m:Tech/Serwer switch]] and if we do, we'll leave a redirect so the link above will be working.
As for the content of the message, we have kept the previous messages, and made small changes. Please review all messages.
More information will be published in Tech News and will also be posted on individual wikis.
Please inform your communities about this event!
Thank you for your help,
Szymon Grabarczuk (he/him)
