- Create new functional group s8, dedicated to wikidata
- Prepare mediawiki and cloud wiki replica configuration for s8
- Provision new hardware, serving exclusively the wikidata dataset
- Refactor puppet/core db to introduce multi-instance for mediawiki hosts (this will be a benefit for the whole db infra)
- Switchover service to the new functional group s8 (master failover)
Only small follow-ups pending: cloud and dbstore replication and other small things.
- dbstore1001 done, but s8 got corrupted, needs reload
- dbstore1002
- dbstore2001 done, respective drops pending
- db1095 (sanitarium)
