Executive summary:
Wikitech may be a bit different today. Please log any new issues here: https://bugzilla.wikimedia.org/enter_bug.cgi?product=Wikimedia%20Labs and select 'wikitech-interface'.
The whole story:
Since the birth of Labs, wikitech.wikimedia.org (formerly known as 'labsconsole') has been managed by hand by Labs operations staff. While wikitech was in rapid development it made sense to keep its off-the-cuff design, but now that it's become a (quite) essential and (fairly) stable part of our infrastructure, it was time to bring it into the fold.
So, as of today, wikitech is running a wiki config that's managed by our deployment infrastructure -- Internally, this is know as being 'on the deployment train.' It's a good place to be -- wikitech will receive more timely updates, and can now be more easily configured by WMF staff and volunteers. But, be warned: since this entailed in a fresh build of wikitech from new code, there are bound to be unintended differences. I haven't found any serious ones, but I bet you will!
Please be on the lookout for new bugs, unexpected changes of behavior, etc. When you find problems, report them using the bugzilla link above. If these issues are urgent (in other words, preventing you from doing stuff that you need to do) feel free to nag one of the involved people on IRC: coren, bd808, reedy, or me (andrewbogott).
Many thanks to Bryan, Sam, Chad, Coren, and all others who helped with this endeavor!
