Okay so one day there was this guy and he was connecting to two different IRC servers and downloading some rather big files on a rather regular basis, and the next day he was not able to join either server anymore. The following day he tried again with the same result. Is it possible for his ISP to see these large transfers and make it physically impossible to connect to those servers? Or is the guy just doing something wrong? The only message he gets while trying to connect to both is an "unable to resolve server" message.
