updates.jenkins-ci.org is terribly slow/down

[Paul Sokolovsky]

Hello,

Today, most attempts to download plugins from updates.jenkins-ci.org
timeout, only sometimes something gets thru. Here're are wget log
examples:

Actually, 502 gateway issues usually indicate that the HTTP proxy is timing out -- meaning the application behind updates.jenkins-ci.org is taking too long to respond.  It's probably working beyond capacity (these are my guesses without being able to actually see anything about it....)

No, it was not me, the logs below were from Europe, and I had the same
issue from Amazon EC2 us-east-1 availability zone (for duration of ~8
hours today). But whoever fixed it after the mail went out, thanks.

Our current hypothesis is that either ci.jenkins-ci.org is putting a lot
of load and making everything slow, or something is eating up all the
connections to Postgres and making mirrorbrain time out.

This morning it is acting as slowly and badly as yesterday morning. I got a 503 trying http://jenkins-ci.org/, and now it is slowly rendering. I got a 504 going to http://ci.jenkins-ci.org/ and now a 503. http://updates.jenkins-ci.org/ is slow.

JIRA is acting fine. Confluence is having issues loading the plugin info on some pages.

Do we have graphite or something running we can check the CPU/Network usage of these machines to make sure we don't have something abusing the systems.
