Howdy, I hope it doesn't hurt too much :rofl: - Only joking.
This sort of outage has happened twice within a week. Last time it was off for about 30 minutes, obviously, its worse this time and when it will come back, nobody knows.
I was also playing two tourney's and I expect that they will return your buy-in, but then again they may give you back the money you have earn't as a % of the chips you have over the total chips in play.
They'll announce something soon, probably best to check on SM, facebook and the like.
Hope this helps.
