Today I cannot start several Virtual Machines. I'm getting 'Failed to start virtual machine' and 'The server encountered an internal error. Please retry the request.' Tried it via the Portal and from Visual Studio 2013. I have to say that I reconfigured these VMs yesterday from Standard Tier to Basic Tier.
One of the operation IDs is f397ee4e-9a53-8a14-a2a8-9324c38b2076
These are single instance VMs and I have no option now to bring online my services.
