Hello everyone

Happy new year!

This is a reminder.

Next Tuesday 9th January at 6:00AM UTC we will have a read only time on s5 for 30 minutes (https://phabricator.wikimedia.org/T181645 ), to proceed and split wikidata onto its own hardware and make the new s8 shard live (https://phabricator.wikimedia.org/T177208).

Amir and Katie have kindly agreed to help us with testing and any possible troubleshooting from the code side.

Communication and coordination will happen on #wikimedia-operations if anyone else is around and willing to provide another pair of eyes, that would be, of course, much appreciated!

Thanks Jaime, Manuel

Hello,

The failover to split s5 and s8 was done successfully ( https://phabricator.wikimedia.org/T177208#3885585) So now dewiki lives on s5 (not changed) and wikidata has its own set of servers in a new shard called s8.

Thanks everyone who helped out!

Jaime,Manuel
