I have a dedicated windows 2008 server and with Allocated monthly traffic: 1500GB, the hosting company sent me "Please take note that the allocated traffic included with your Budget (calculated by GB of traffic) has been exceeded. You will be billed for the exceeding traffic at the end of the month according to the per GB exceeding traffic fee specified on your contract."
I checked my Google analytics account and didn't find any big different for the websites traffic this month than previous months.
I just want to understand what may cause this sudden increase in traffic this month?
may be ftp access? remoting to webserver too much time? or what may cause this?
Also, is there any tool in the server to know where the traffic went?
