The full updates from their sub:
System Wide Outage Alert and Updates
UPDATE 1 : 6:00AM EST
This looks like a major outage. Almost all servers are offline. I don't have anymore information at this point, it looks like the servers were taken down by data centre provider because of maximum load during the game.
As soon as I know something, I'll post more. At this point it's not looking good. 😞
Update 2:
Sky Sports F1 SD has been moved to a temporary server. All other streams will remain offline for now
Update 3: 9:00 AM EST
Most streams are back, but we have very limited capacity. Expect buffering.
New servers are being rebuilt. No ETA at this point.
Update 4: 11:30AM New servers are still being worked on. Some should be online soon. VOD is gone and it will need to be rebuilt from scratch. :(
