Just a quick reminder that this is now live. Wikidata is no longer on s5, both on production and wikireplicas, and you should connect to s8 (or much better, use the "wikidatawiki" dns entry) to get results related to wikidata.

As a side note, right now if you connect to any "s*" alias, you will likely be on the same server- that is why this is unlikely to affect you-, but in the future we may run out of space (we are currently at 7.8TB used out of 12TB) or other resource and we may have to separate the different "s*" wikis, so please do not assume that will be true forever (it is not supported).

On 2018-01-09 the wikidatawiki database will move from its current
home on the "s5" slice to a brand new "s8" slice. The
wikidatawiki.{analytics,web}.db.svc.eqiad.wmflabs and
wikidatawiki.labsdb DNS service names will be updated to point to the
new slice host by system administrators. This change should not affect
most users of the Wiki Replica servers.

Only applications that are connecting to
s5.{analytics,web}.db.svc.eqiad.wmflabs or s5.labsdb and expecting the
wikidatawiki_p database to be present will be affected. These
applications should update their configuration to connect to the new
"s8" slice instead.

This is the end point (or nearly so) of a large amount of work that
has been done by Wikimedia's fabulous DBA team of Jamie and Manuel to
improve the health of the Wikidata wiki. See
