Yeah, I noticed some instability yesterday. When I looked at it, it was someone creating large workspace zip files and appear to be retrying many times, effectively creating an DoS attack.

I'm not sure if this outage is related, but I just restarted it.

Same here.

Here are my details for one of you who can help debug further and
resolve this; thanks!

HTTP error 504 on Chrome, Chromium, Firefox, Internet Explorer.

I tried:
http://ci.jenkins-ci.org/
http://cucumber.jenkins-ci.org/
http://63.246.20.93/
http://63-246-20-93.contegix.com/
http://web.archive.org/web/http://ci.jenkins-ci.org/ (this only has a
capture from Feb 8th, 2011)

I noticed that HTTP / TCP 80 is listening according to `telnet
ci.jenkins-ci.org <http://ci.jenkins-ci.org> 80` and `nslookup
ci.jenkins-ci.org <http://ci.jenkins-ci.org>` is resolve-able.
