NOTE: This post has moved to https://blog.gibson.sh/2010/06/30/bug-hunting-browsers-fail-to-load-research.microsoft.com/
The original article is kept here for now, but is not maintained in any way.
This is a follow-up to debian bug #541658 for Iceweasel: “cannot open research.microsoft.com”.
It turned out that this bug applies to all (tested) browsers with cookie-support (Iceweasel, Opera, Chrome, Arora, Kazehakase), but only very few people are experiencing it. If you’re one of them please get in touch via the comments :-)
First I’ll tell how to reproduce the bug, then I’ll sum up the facts I already collected in that bugreport and then I’ll document my further attempts to narrow down the problem.
UPDATE: The reason for that strange behaviour was found and I filed a new bugreport: No. #587789
UPDATE 2: Debians Kernel maintainer considers this expected behavior and told me to file a bugreport upstream and I did: Netfilter bug #622.
UPDATE 3: I think Microsoft has fixed their server. Of course the Linux kernel should be fixed anyway but there doesn’t seem to be much interest in doing so :-/
