moneyman,

Maybe you should check again. Almost all the carriers and datacenters which offer bandwidth also offer unmetered ports. Unmetered and 95th percentile are two different things. 95th percentile allows you burst up to a certain speed for a certain amount of time in a month (36 hours) while on an unmetered port, you cannot burst.

Say you get a 10Gbps unmetered port from Cogent, they cannot bill you for extra bandwidth, right? You're committing to 10Gbps on a 10Gbps port, how can you burst more than 10Gbps? So even if you're using 10Gbps all times, you don't get billed for it because it is "unmetered". But if you're getting 1000Mbps commit on 10Gbps port being billed by 95th percentile method, you can use 1000Mbps all times, but you can "burst" more than 1000Mbps when required for 36 hours in a month, so it's called 95th percentile.
