Connection lost

I was playing on May 4th at about 2am. My friend lost his connection he is on DSL connection. It did not only happen once but twice. Now he didnt lose internet just game. It has happen to me once. Anyone know the reason be hind this.

I cant find a reason...it happens to me too, usually during a hard mission >_<

I asked tech support but they just said "we are looking into it", thanks guys.

Ya i know what you mean but the mission wasnt hard and you would think that it would kick the whole party. oh well
