This is about eventually decommissioning the alternate hostname entrypoints for these services. Going forward, these should all be using /api/rest_v1/ on the wiki domains themselves.
- rest.wikimedia.org - Removed, 2016-09-01: https://lists.wikimedia.org/pipermail/wikitech-l/2016-July/086116.html
- citoid.wikimedia.org - Removed, 2017-05-01
- cxserver.wikimedia.org - RB conversion still TODO
- everything else from below - already dealt with and gone.
Quoting from the wikimedia.org DNS zonefile, the current list of these entrypoint hostnames is:
;;;; cxserver/citoid/rest(base) below are LEGACY, to be removed eventually cxserver.eqiad 600 IN DYNA geoip!text-addrs cxserver 600 IN DYNA geoip!text-addrs citoid.eqiad 600 IN DYNA geoip!text-addrs citoid 600 IN DYNA geoip!text-addrs restbase.eqiad 600 IN DYNA geoip!text-addrs restbase 600 IN DYNA geoip!text-addrs rest 600 IN DYNA geoip!text-addrs
There's also some varnish code in support of these on the text cluster.
I'd like to start with pulling the .eqiad. subdomain entries - these should never have been used publicly and probably aren't now, and we can try to confirm that with traffic logging and code searches (aside: perhaps we should do better messaging within the org that any hostname in a datacenter-specific public subdomain is purely for infrastructure tracking/debugging, not for use as an official service hostname).
