On September 1st, all the traffic from the wikis will be switched to the secondary data center (like we did in 2018). It means that all wikis will be on read-only mode on September 1st 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=

More information will be published in Tech News and will also be posted on individual wikis on week 35 (starting Monday 24). Please inform your community about this event!

Thank you for your help,
