This is the current update from the BB team: "We have resolved the current issues with the platform. Our workers are slowly working through a fairly large backlog of requests that have been pending since the issues originally started. Things are continuing to stabilize, but will take another hour or 2 before things are back to normal and your requests are fully processed."
Update: "Partial service has been restored. Repository clones and pulls should complete without problem on HTTPS as well as SSH. Pushes and pull-request updates are still functioning at a limited capacity and may not work as expected for some users. Sep 2, 15:05 UTC"
So ~2 hours from "investigating" to "identified"... not a terrible response.
It looks like SSH is completely down, and some people can't connect over https either. Overall status page:
Yea... it's really bad. I was hoping someone in the NH community had deeper knowledge of the problem. Curious if it was a DoS attack similar to those launched against GitHub a while back.
