On a test browser instance I visited https://en.wikipedia.org, and clicked Log in. I used a WMF test account (SpageTest AC 0618-1) that I probably hadn't used since June. Login displayed an unexpected failure from http://wikimediafoundation.org/wiki/Special:CentralLogin/start?token=TokenHereBlahblah , "No such special page". I was actually logged in to enwiki. Note the URL above is CentralLogin/start, not CentralAutoLogin/start, I think I copied and pasted it from the browser location bar. I logged out and repeated the login, with Firebug active. This time I logged in fine. There was still a 404 in the Net tab but it didn't display as a failure and it was from http://wikimediafoundation.org/wiki/Special:CentralAutoLogin/checkLoggedIn?wikiid=enwikisource&type=1x1&from=enwiki I logged out, cleared my cookies, and went back to enwiki and logged in; this time there were no requests to wikimediafoundation.org Maybe this is a remnant of some old-style login cookies.
I filed this as a Wikimedia config bug, but now I see bug 52206 describes the same scenario. *** This bug has been marked as a duplicate of bug 52206 ***
