Hello,
Next week, 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/Server 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)
