Hi Folks,
This morning we had an unplanned outage of the NGINX proxy inbound to ci.centos.org.
We were able to reboot the machine, and add some resources to help us better handle the inbound traffic. Thanks to Fabian for doing that!
We've seen this behavior once or twice before, where inbound http connections fail intermittently. During those periods and during our emergency maintenance, connections internally between the slaves and the jenkins master remained up and no jobs were interrupted.
If you have any questions, please let us know here on-list or in #centos-devel on freenode.
Cheers!
