Is the service bus undergoing some kind of maintenance? It has been extremely unstable to the point of being essentially unusable for us for the last few days. (Getting generic server errors, unable to connect on port xyz, server actively refused connection, hangs, timeouts and all manners of general instability). I thought this might have to do with my app, but I tried running the echo samples with a server and a few clients, and experienced the same patchy performance.
