Consider storing the information on wikitech wiki. Since there is wikitech-static which is a copy of that and kept completely outside normal WMF infratstructure for this very reason, to be available in the event of a disaster.

jcrespo moved this task from Triage to Blocked external/Not db team on the DBA board.

note: the steps are a bit different for failing over between data centers vs within a single data center.

From @Dzahn via IRC:

07:48:42	<mutante>	for eqiad/codfw parts of it are all prepared in hiera
07:48:47	<mutante>	and applied per dc
07:49:02	<mutante>	for eqiad we have IPs applied via hostname
07:49:08	<mutante>	for codfw by role
07:49:23	<mutante>	this inconsistency was actually nice for a switch to phab1002 in this case
07:49:35	<mutante>	i could just set other IPs for phab1002 also by host
