We are currently seeing some connectivity issues to parts of our Dallas datacenter network. We are working to isolate the cause of that now.

Update: There was a server in our network that had been exploited and was causing a denial of service.  We have resolved that.  And we are looking at increasing the network capacity to avoid this being a problem in the future.  It only affected a minority of servers, those not on our gige network feed.

Update @1947UTC: We detected another flood. We have found the source and stopped that. Packet loss has returned to normal levels.
