OK I new here but this seems to be the place to asks so here goes.
Where do you host stuff that needs lots of bandwidth. In the 12-45 Gig a day, 300-700 gig a month range. The BBS on thsi site alone hits 6 gig every day so there is some serious database access going on and lots of PHP to render pages for between 200- and 500 users, but to be honest the machine isn't the problem it is the bandwidth is and always has been the big cost.
Hosted with 1&1 currently which is getting just a little expensive.
