Callouts

 * Data Centre Switch 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. More information: https://lists.wikimedia.org/pipermail/wikitech-ambassadors/2020-August/002344.html
 * No train next week There is a planned switchover to our secondary datacenter scheduled for Tuesday, September 2nd 2020. To avoid creating problems for our SREs we'll be skipping the train for next week -- the week of 2020-08-31 -- and not doing any deployments the day of the switchover -- 2020-09-01.
 * scap sync now called scap sync-world There is a new release of Scap (3.15.0), which will be installed on the various servers next week. More information: https://lists.wikimedia.org/pipermail/wikitech-l/2020-August/093749.html.
