Oh, and to clarify about your question about "unmetered":
What I mean by that is that the amount of bandwidth committed to your account (your "commit", we call it), gets you a guaranteed capacity for that traffic in both directions, and you pay a flat monthly rate for that amount.
Typically, we cap your switchport at whatever amount your commit is set to (25mbps in this case), so it's impossible to incur overages. However, it is also possible to request your port to remain uncapped, giving you the ability to utilize either 100 or 1000mbps, depending on the model of the switch your server uplinks into. This setup is commonly referred to as a "Burstable" connection. The caveat of this is that if your 95% usage exceeds your commit, hosts charge an overage fee of $x/mbps, for every mbps over your commit that you use during your billing period.
I hope this helps!
