Yes, Fooks is right. You got attacked by the infamous Ddos which=gay. Those people deserve to be shot. I got a nice little Ddos attack a few months back and my entire internet was down for about 5 hours.
5 hours? LOL just reset your modem and you're back up in 2 minutes.
I learned that real quick because i didn't want my new modem to suffer damage like my old one.... don't even ask.

I remember sometimes I would be playing Halo 3 some ass hat saw my gamer tag and immediately hit me offline before the game because they knew i was better; so they had to cheat to rank up... It happened as often as every other game. I played tons of halo about 3-4 years ago and I played against pretty much the same 500 people (but on different accounts)
