This service is still in eqiad.
It was not covered by other tickets. It has its own dedicated backends but can also be failed over. (or can it not?)
If it can't, we shoud add reasons that block it. The default should be that everything switches over at each DC switch. needs justification to opt-out.

[operations/puppet@production] doc.wikimedia.org: switch active host from eqiad to codfw
Mentioned in SAL (#wikimedia-operations) [2023-03-02T01:23:38Z] <mutante> doc2001 - stopping apache2 to test alerting - active server is doc1002 but should be switched T327973 T330963
@hashar Is there a ticket for "work that needs to be done before doc hosts can switch data centers"? That would be great. Then I could use that here to set this stalled on it and it would make things clearer for next switch. Thank you!
Change 893579 abandoned by Dzahn:
[operations/puppet@production] doc.wikimedia.org: switch active host from eqiad to codfw
Reason:
could not happen during last switch over and we are about to go back to eqiad soon anyways now. but it should still be made clear if it COULD switch and for next time. so see https://phabricator.wikimedia.org/T330963#8755826 please
