Codfw external storage servers es2001-es2010 are already removed from MediaWiki configuration (db-codfw.php), see T127330.
- es2005-es2009 are still replicating from the local master, until they will finish the space in few days, just in case
- es2010 has hardware issues, see T127769
- I've already scheduled downtime until 2016-12-31 and disable notification for all of them on Icinga to avoid unnecessary pages
Before proceeding please get final confirmation from the DBA team.
