We currently don't have any servers with the mediawiki::appserver::canary_api and mediawiki::appserver:.canary roles in codfw. I'm pretty certain we had those in the past, but maybe there got dropped by means of hardware refreshment?
Given that there's a DC switchover coming, we should fix that.
canary appservers codfw:
mwdebug2001 (row A, ganeti VM)
mwdebug2002 (row B, ganeti VM)
mw2163 (C3, physical)
mw2164 (C3, physical)
mw2271 (D3, physical)
mw2272 (D3, physical)
canary API appservers codfw:
mw2215 (A3, physical)
mw2216 (A3, physical)
mw2244 (A4, physical)
