MSSQL11 will be up in a moment however it seems there is an issue on the node this server on. I am preparing new space for it now and we'll have to do an emergency maintenance on it to shut down proper and move the files, in a couple of hours. It won't be the best timing for a move, but knowing it is coming and getting the matter resolved will be better than continued random problems on the server.
This server is not on the cloud platform but a single node install, so there will not be other servers also down with it, except website that use SQL services from it, which will benefit from the new hardware stability and platform.
