I frequently get this message, when I try to open the forum, display a question or post an answer:
Bad Request
Your browser sent a request that this server could not understand.
Size of a request header field exceeds server limit.
Cookie: X_MW_DOMAIN=mathworks.com; MW_AL=5c9a...
The problem appears in about 50% of the cases and I see it since about 32 hours. I have to click on the "Save" button twice most of the times, before something happens, and about half of my answers (and another version of this question) vanish.
Is this known already?

I don't think so. I usually leave my home computer logged in (though sleeping) when I leave in the morning and then login here at work with no problems at all (other than slow page retrieval). So we're back to you personally. Maybe you should change your avatar? :-) Maybe try running it though http://www.effmypic.com/ or something.

We are investigating the Bad Request issue that Jan reported--other users have experienced similar problems in other areas of MathWorks.com.
Clearing your browser cookies should resolve the problem, though in some cases (such as Jan's) this fix is only temporary.
I will update this Answer when we resolve the problem.
Sorry for the inconvenience!

Any progress on the issue that access to mathworks.com/matlabcentral/answers and documentation is quite slow ? I've switched to using the .co.uk site to access answers, but the .co.uk site redirects documentation requests to .com for me so I cannot do the same for documentation. Fetching simple documentation pages often times out for me.
www.mathworks.com resolves to e218.b.akamaiedge.net which resolves to 23.14.96.244 for me (the exact IP resolved to is geographic dependent so it is possible for two people in different cities to get different results, if, hypothetically, something were wrong with only some of the akamiedge servers)

We are working on a handful of performance fixes in Answers, but slowness from those problems should be similar from one domain to another.
I will look into whether there are any known issues related to doc or .com performance...

I haven't been able to track down a specific cause, but it looks like some MathWorks server(s) set a cookie that was overly long.
If this problem recurs please send me the contents of your MathWorks cookies before deleting them: $firstname.$lastname@mathworks.com
