https://doc.wikimedia.org/mediawiki-core/master/php/html/ linked from https://doc.wikimedia.org/ is giving me 'infinite redirect loop'.
WFM
Works for me too. Browser info etc needed.
Worked once for me when by-passing cache, but it is there again. Seems to be intermittent?
Pau was able to reproduce. We are both using Chrome.

Sounds similar to bug 56842. FWIW, I've never seen such problems with Chromium and I can't reproduce in this case either (only tried a dozen times though).
Cannot reproduce either with Google Chrome 32.0 on Fedora 20.
Created attachment 14482 [details] Proof in two browsers It's not a browser related. It doesn't make a sense unless there is a broken server behind load balancing to explain why this problem is intermittent.
The integration websites have been migrated behind the misc-varnish box so pages ends up being cached there. Using Chrome development tools, can you grab the response headers? Also if you try the page and append a cache breaker (i.e. ?sometimestamp), that should serve the page.
FWIW I hit this issue this morning, but was unable to reproduce after opening Firefox's web console once.
This has been happening for little over a week now. Ever since it was changed from being served from misc-web instead of gallium, something got messed up in the dns or apache config that causes it to get stuck in a redirect loop sometimes. It seems to usually be mitigated by chance (e.g. change the url with a bogus query param, or flush local dns cache).
Recent changes that might have contributed to this problem; operations/dns: doc and integration.mediawiki.org go to text varnish, not misc Change-Id: I62d29d9c552acd86b29663eb961d67b21fddf1e5 - fix cname for doc.wikimedia.org Change-Id: Ie483903b6f77270a4295672b5a0a5f6a2375e3e4 RT: 6594 - moving doc.wikimedia.org to misc-web-lb Change-Id: Ie80551a532dbc32cbc9c0d73c396e88f63fcb0b3 RT: 6594 - operations/puppet: doc.wikimedia.org and doc.mediawiki.org to use misc-web-lb moving https termination from gallium to the misc-web-lb. this change will go live at the same time as the dns change Change-Id: I2fe62629f4deaf4c1ace4345ba7c743b84469fd9 RT: 6594
