The Wikimedia Foundation will be testing its secondary data centre. This will make sure that Wikipedia and the other Wikimedia wikis can stay online even after a disaster. To make sure everything is working, the Wikimedia Technology department needs to do a planned test. This test will show if they can reliably switch from one datacenter to the other. It requires many teams to prepare for the test and to be available to fix any unexpected problems.

They will switch all traffic to the secondary data centre on Tuesday, September 1st 2020.

Unfortunately, because of some limitations in MediaWiki, all editing must stop while the switch is made. We apologize for this disruption, and we are working to minimize it in the future.

You will be able to read, but not edit, all wikis for a short period of time.

Other effects:

This project may be postponed if necessary. You can read the schedule at wikitech.wikimedia.org. Any changes will be announced in the schedule. There will be more notifications about this. Please share this information with your community.

Let me know if you have any questions!
