The problem hasn't gone away yet (just got a timeout on a preview of a long test message), but at least I can post short messages again (after deleting the session cookies).

client_header_timeout  25s;
How is that?

Nope, I still get the "HTTP/0.9 200 OK", empty response. The site does seem faster though.

Can NGINX log raw incoming HTTP headers or only field-by-field (which might be too late in case of a HTTP-400)?

How much work would it be to set up a test environment ("test.animenewsnetwork.com", the domain is already visible out there) with all NGINX configurations identical to "www.animenewsnetwork.com" except for server logfile settings for HTTP headers & cookies to the maximum (and maybe a different port number to listen to so that you could use a port scanner for this one to trace the incoming headers if all else fails), and let only users with problems surf there? This way you might get a maximum of trace data with a minimum of server logging overhead (plus restrict the effect of any experimental NGINX settings to the "test pilots").
I'd expect to observe HTTP headers truncated at a much smaller threshold than the NGINX settings, thus clearing the server from the list of suspects.

I've already setup Nginx to log errors at the debug level, and even then I don't get much. All I've been getting are errors like
Code:
2010/05/27 20:08:52 [info] 88007#0: *37243 client timed out (60: Operation timed out) while reading client request line, client: 173.74.10.25, server: 0.0.0.0:80
Code:
2010/05/27 20:09:49 [info] 88006#0: *37281 client timed out (60: Operation timed out) while reading client request headers, client: 173.74.10.25, server: localhost, request: "GET /images/system/my-seen3.png HTTP/1.1", host: "fast.animenewsnetwork.com", referrer: "http://fast.animenewsnetwork.com/MyAnime/"

Most of the errors are of the first type, meaning that even if Nginx was able to log raw headers (which AFAIK it can't), it wouldn't have anything to log; the request times out at the request line, before any headers even come in!

I googled a bunch of variations on those errors but nothing useful came up.

Still the same Confused

Did anything change at your provider perhaps? On Tuesday (see earlier in this thread) things worked for a while.

Yeah, the issue is still here. I have also sent an e-mail to encyclopedist@ANN. Hope it helps.

According to "Live HTTP Headers" add-on I also get stuck at "HTTP/0.9 200 OK", so it's two people getting same error now. At least that should help.

PS: Posted with Chrome.

Make that three. Also forced to use Chrome to have a normal navigation through ANN.

Subscribers are probably the ones sending more feedback about the situation because they should normally have stronger ties to the ANN community. If non-subscribers encounter difficulty in accessing the encyclopedia or the forums, I seriously doubt they will take their time to make a report. They will just move towards other options like Wikipedia and AniDB.

Right now, fast. for me is not fast at all. www. is even faster than fast. I've been using bel. almost exclusively, as it seems to be normal relatively. I usually never log out of session for days - dunno if that has something to do with it. There has to be a way to turn off my subscription option so it doesn't redirect me to fast. automagically.

I tried www just now. It takes a little longer to timeout, but gives the same "HTTP/0.9 200 OK" result Confused

The problem (or what we know of it) has been fixed. Please let us know if you still encounter any 400/500 error messages, any time-outs or any very slow performance.

Someone must have dumped RedBull onto the servers because these things are fast. I don't think I've ever seen the site run so fast.

Kudos, and thanks to all for the fix. Oh, no problems on my end. Smile
