Pokerstars are now advertising that any SNG affected will be rolled forward after the next server restart tomorrow. For anyone interested i got this from the pokerstars terms and conditions – so basically money back and a bit of ICM depending on where the tourney was at the time it froze

Roll Forward (No Players in the Money)

If a tournament is cancelled and we do a “roll forward”
before the players are in the money, we refund each remaining player
his tournament fee (and knockout bounty if appropriate), and then
divide up the prize pool based on the following formula:

• 50% of the award pool is distributed evenly among all remaining players
• 50% of the award pool is distributed proportionally according to the chip count

Here's an example:

You were in a $33 ($30 entry +$3 tournament fee) buy-in
tournament (with rebuys). There were initially 200 players, and with
rebuys the total prize pool was $9000. Suppose at the time of
cancellation there were 100 players remaining, and your chip count was
37,500. The total chips in play were 300,000.

Prize pool to be divided equally: $9,000.00/2 = $4,500.00
Prize pool to be divided based on chip count: $9,000.00/2 = $4,500.00

Your share in money equally divided: $4,500.00/100 = $45.00
Your share based on chip count: $4,500.00 x (37,500/300,000) = $562.50
Your tournament fee refunded: $3.00

Total money refunded to your account: $610.50

Note that if you bust out before the tournament is cancelled, you receive no refund.

When we do a “roll forward”, all refunds are in cash (not T$).

Roll Forward (Players are in the Money)

When a tournament is cancelled, and players have already
reached the money, we refund each remaining player his tournament fee
(and knockout bounty if appropriate), and then divide up the prize pool
based on the following formula:

• Each player receives the minimum prize not yet awarded at the time of cancellation
• The remainder of the award pool distributed is distributed proportionally according to the chip count

Here's an example:

When the tournament was cancelled, there were 15 players
remaining, and your chip count was 37,500. The total chips in play
were 300,000. The remaining prize pool was $11,000.00 and the minimum
prize was $250.00.

Prize pool to be divided equally: $250.00 x 15 = $3,750.00
Prize pool to be divided based on chip count: $11,000.00 – $3,750.00 = $7,250.00

Your “minimum prize” share: $250.00
Your share based on your chip count: $7,250.00 x (37,500/300,000) = $906.25
Your tournament fee refunded: $3.00

Total money refunded to your account: $1,159.25

Note that if you bust out before the tournament is
cancelled, you receive no refund of your entry fee. Of course, if you
placed in the money before the tournament was cancelled, you keep that
money.

Heads-Up Sit & Go Tournaments

Heads-up Sit & Go tournaments (HU S&Gs) are
handled differently because of their special nature. Particularly if
one player stays connected while the other player does not, the first
player can effectively win the tournament while the second player is
disconnected. For that reason, we reserve the right to do a chip count
distribution of any HU S&G that we believe was substantially
affected by our site's downtime.

I got up at 4am, pumped myself full of caffeine ready to grind these and then found out they were broken 🙁
