Mirror, mirror on the wall

R. Tyler Croy July 18, 2011

Let me preface this entire post with this: I love Contegix.

While working on some infrastructure tasks I had long-since put-off for the Jenkins project, I noticed something this weekend that scared the hell out of me.

At some undetermined time, our MirrorBrain installation stopped redirecting to our mirror network. Absolutely zero downloads were being redirected, meaning that cucumber, the 1U machine graciously colocated by Contegix had served up far more bits than I ever wanted it to.

As such, I would like to publicly apologize to Contegix on behalf of the Jenkins project. Their support for the project has been tremendous but this glitch caused such an incredible amount of traffic to be pushed through their network that I feel exceptionally bad about it (turns out, Jenkins is pretty popular!)

Now, for the good news. In diagnosing and debugging this issue (in a caffeine-fueled frenzy I might add) I managed to do a couple things:

I corrected the redirection relatively easily
I fixed our long-standing geo-location issue, finally enabling redirection to our european and asian mirrors!

Within 30 minutes of correcting the error, I was able to add two mirrors in Germany, re-enable one from Taiwan and add a new mirror in Japan!

I’m hoping to add even more mirrors in even more regions as volunteers with bandwidth step-forward, if you’re interested in hosting a mirror you can drop me a line at tyler@linux.com.
