Now that T137838: setup phab2001.codfw.wmnet (WMF6405) is done, it's time to get some redundancy in phabricator.
There are a lot of pieces to this and most of these will eventually split off as subtasks but I'm writing them here for now:
- get phabricator puppet roles working 100% on jessie
- figure out how to get email working from codfw
- mirror all repositories to phab2001.codfw.wmnet
- prepare a disaster recovery plan for failing over from phab1001 to phab2001 (or phab2001 to 1001)
- rename iridium to phab1001.eqiad.wmnet
