said by ArrayList:what game servers do you run? I run a very active tf2 server and it barely uses 50gb per month. That is not a lot of data.
I ran a somewhat active Minecraft server for a while, it used like 150-250GB per month of bandwidth.
I recently shut it down after nearly three months of daily DDoS attacks (reaching into the 4Gbit range at one point). I'm glad I didn't run it at home, it would have been 1000x worse to deal with.
