Based on http://wikitech.wikimedia.org/view/Server_admin_log

I did it on the 1st of March and on the 22nd of March

Yeah, I was pretty sure we'd already done it because we've recently added some gerrit interwikis. I think that "last known" date is wrong.

Thanks for the information, the only information that has been evident of the last update is when someone updates the annotated line on th page. I will make a note about where and for what admins can look for this information.

It would be useful if there was clarity on the pathway that those with shell access expect requests to follow for updates, or an indication that there is a process that exists to have the file updated on a regular basis.

submit one via gerrit?

Gerrit isn't involved here.

Old bug: interwikis have been rebuilt several times in the meanwhile.
