I have an Azure VM at 168.63.211.138 that has been working fine, but all of a sudden no longer works at all. SSH, Ping etc time out, so I can't connect to it at all. Endpoints are set correctly, and have been working fine till now. The portal status shows it as 'Running' though, and I've tried both restarting and shutdown/start from within portal to no effect. It's a Linux VM running only MySQL, nothing very demanding.
Any idea what's going on, or what I could do to fix it? All my sites are down because of no MySQL access :(
