Do we have any DNS or varnish/apache stats of hits to these URLs?

Presumably they're still not needed, but I honestly couldn't tell you the amount of people still using the old redirects.

Due to the nature of the wikis, at worst, we could just email all the users of them to inform them that the old urls are going to stop working, so if they still have any bookmarks (the 90s called), to update them...

Thanks @faidon. Is there a time period as to when those hits were made? It would seem arbcom-(de|nl|en) are the main ones to worry about notifying...

No need to worry about these. arbcom-(de|nl|en).wikipedia.org can be covered by the certificate (*.wikipedia.org). Probably the 5 hits for arbcom.en.wikipedia.org is worrisome, since about 6.8% arbcom-en requests were made to arbcom.en first. Notifying English Arbitration Committee is easy anyway, maybe by emailing their mailing list: https://lists.wikimedia.org/mailman/listinfo/arbcom-l.

Right, there's no real cert issue for any of these, it's just a matter of notifications.

Remove old double-subdomain aliases

https://gerrit.wikimedia.org/r/224309

Might be worth looping in @Philippe-WMF and/or @Jalexander as they should have contacts within those communities

And then we need a patch to the apache config to remove the old redirects/rewrites :)

Have these communities been notified yet?

no; will do tonight.

They're notified. :)

Confirmed. Arbcom-en has been notified.

Woo, thanks!

Out of interest, what exactly did you tell them? Just wondering so we can plan to remove these domains in X time etc

We told them we'd remove it soon :) specifically no time frame. I would wait until Monday or Tuesday to ensure they've had a chance to see it but no real reason to wait much longer.

Sounds like a plan. Wait a few days, get ops to check again for requests for it, and then proceeed to cleanup. Yay

The English Wikipedia Arbitration Committee moved from arbcom.en.wikipedia.org to arbcom-en.wikipedia.org (see T33335). As long as the new hostname continues to work (the one that isn't a subdomain of en.wikipedia.org), we're fine with the move.

Yeah, these are just redirects from the old names that would cost quite a lot of money to actually support fully because of the ssl certs etc.

The pa.us issue is in wikiMedia.org, which has a separate ticket here: T102826
This ticket is just tracking wikiPedia.org, which just has the 5x records listed at the top of this thread (the 4x arbcoms + wg.en)
