We are currently experiencing an unscheduled service outage on websrv01 due to what we believe may be a hardware issue on the server. Unfortunately our co-location provider misconfigured the power port that our server is plugged into, so we were unable to reboot the machine ourselves. Currently we have a technician assigned in Montreal who is on his way to the data centre to reboot the server and investigate further. We will update this post as more information becomes available.

Update 3:53PM
We are still working with our co-location provider to determine the exact cause of the problem. One theory currently being investigated is that we may be experiencing a distributed denial of service attack on the server. As soon as we have any further information, we will post it.

Update 6:20PM
The problem has now been resolved, and all service has been fully restored. It does in fact appear to have been a distributed denial of service attack, which fortunately ceased on it’s own. We sustained 1Mbit of http traffic to websrv01 for only a short period of time before the server was unable to handle the requests. The 1Mbit wall continued until just after 6PM when it stopped just as mysteriously as it began. Further investigation is on-going and any new information will be made available.

We apologize for the inconvenience.
