Because of a data centre test you will be able to read but not edit the wikis for up to an hour on 10 October. This will start at 14:00 (UTC). You might lose edits if you try to save during this time. The time when you can't edit might be shorter than an hour. You can read more about this.
Because of the data centre test there will be no new version of MediaWiki this week. Changes for this week will come next week instead.
