[Labs-announce] New Wiki Replica servers ready for use

[Bryan Davis]

After more than a year of effort by the DBA team, a new set of Wiki
Replica servers are ready for full use by Cloud Services users. The
new servers are faster, have more disk space, and are using updated
software and configuration that corrects many historic problems with
replica drift and security.

See the technical blog post for full details: <>

TL;DR:
- Change your tools and scripts to use:
  - `*.web.db.svc.eqiad.wmflabs` (real-time response needed)
  - `*.analytics.db.svc.eqiad.wmflabs` (batch jobs; long queries)
- Replace `*` with either a shard name (e.g. `s1`) or a wikidb name
(e.g. `enwiki`).
- The new servers **do not** support user created databases/tables
because replication can't be guaranteed. See the blog post for more
information.
- `tools.db.svc.eqiad.wmflabs` (also known as `tools.labsdb`) will
continue to support user created databases and tables.
- Report any bugs you find with these servers in Phabricator using the
#Data-Services tag.
