On October 27, all the traffic from the wikis will be switched to the secondary data center (like we did in 2018, and on September 1st, 2020). It means that all wikis will be in read-only mode on October 27 around 14:00 UTC, for up to 60 minutes.

A message to inform our communities has been written, to be sent to wikis: https://meta.wikimedia.org/wiki/Tech/Server_switch_2020
Direct translation link: https://meta.wikimedia.org/w/index.php?title=Special:Translate&group=page-Tech%2FServer+switch+2020&language= &action=page&filter=

I overall kept the previous messages, but I made some small changes, and added one message. Please review all messages. 

More information will be published in Tech News and will also be posted on individual wikis on week 43 (the week before, starting on Monday 19). Please inform your community about this event!

Thank you for your help,
