How long does server reboot/update take?

[BlueBerry]

I was playing and the server went for a reboot. When can i expect to play again?

Edit: The server is up now, took about 20 minutes.

Sorry this cannot be communicated so easily - most of the time I am left with a Windows update doing it's thing for a long time. I always do it as fast as possible!
