For the POTD, with those two it is understandable. For the DC one, I agree with the tank for waiting 5 more minutes. The last dungeon I was in both the tank and I d/ced. I got back first, but the tank never came back. In the end, our group decided to vote abandon due to the nature of the DDOS attack. You should have done the same, and you wouldn't have gotten the penalty.
