Managed to get a little play time in when VS came back online. However it was very flacky and fragile. Had to reload/refresh and clear DNS cache multiple times. Obviously it was an issue for others too. In the end, and after a couple of hours, in the middle of a spin, VS shat itself. A page refresh greeted me with their Maintenance Holder Page, notifying the site wont be back up until around 06:00 AM CET. Contacted support who informed me it would be Sunday (tomorrow), before they are back online again. No signups... least now you'll know why I thought a 12 hour upgrade window was a bit too optimistic, given what needs doing.
