If the hand history shows that ALL players were disconnected, call Bovada/Ignition and complain.
They will issue you a refund for the money you put in, provided that it's clear to them that all players were knocked off by their server.
This happened to me tonight, as I was on the SB ($15) at a $30/$60 limit holdem game, and their server screwed up and booted all 3 players off.
I called, they looked into it, agreed it was due to server trouble, and refunded my $15.
