its not a matter of if, the isp is the middle man between the runuo servers and the internet, if you attack runuo of course the isp gets hit as wellVlad_The_Impaler said:
It kinda makes me wonder, if the ISP is being attacked and not just specificly aimed at a particular port (Demise itself) then the ISP should be doing an investigation itself since I'm sure demise isn't the only thing on it's servers. I kinda would like to know which ISP so that i may remember not to use it for any of my web serving needs.
Of course this is meant only if the server is being run by a commercialy available buisness.
