What is the accepted usage of unlimited bandwidth with the Data center network?

The accepted usage of unlimited bandwidth on the datacenter IPs is defined as up to 100GB per IP per Month.

In cases where excessive usage of unlimited bandwidth is detected, you will be informed via email so that you should adjust the amount of allocated IPs in your zone to fit your traffic volume or move your plan to Pay per IP
