No warning at all they shouldn't have tournaments running for 3+ hours when they update it. I contacted CS to ask if the tournament was suspended or cancelled and they said that it was cancelled for an "emergency update" I didn't ask what the emergency was as I doubt they would have that information anyway and they probably would of said what it was if they did or were at liberty to discuss it lol
ICM= Independent Chip Module which assigns $$$ value to tournament chips they credited my account with $6 when I got back on and it was a $2 tournament so I got a $4 profit (wasn't happy about it but whatever) so I assume that they gave me a money value of where my chip count was
EDIT: Just incase any one was wondering what is with the thread title it's from a long time ago found
