Each Dedicated server @ FastServers.Net is provided with 300GB of "Actual" transfer per month. Dedicated servers can continue to use the "Actual" bandwidth measurement until 5 MB/s is reached, at which point a conversion to the 95th percentile will be made.
yes but you are generalising a bit with bandwidth calculations like that. For example if you host streaming media or similair then you could peak high loads at various times within a month. I suppose it depends on what your hosting, but its something to think about.
