Hi,
This week's datacenter switchovers went very smoothly overall, in total we had 2 minutes and 42 seconds of read-only time when switching MediaWiki from the codfw to eqiad datacenter, which is pretty close to the 2 minutes we were aiming for.
The main follow-up task from today is that our cache warmup process needs to also warmup some Wikidata caches: https://phabricator.wikimedia.org/T290989.
Yesterday we also switched over various services, the main follow-ups are that we want our cookbook automation to support pooling services in both datacenters (active/active): https://phabricator.wikimedia.org/T290919, and that we have so many services that the list no longer fits on one IRC !log line: https://phabricator.wikimedia.org/T285709.
