said by Wilsdom:It's not "max allowable", you pay for what you use and get to burst above that 5% of the time. 36 hours out of the month you can use as much bandwidth as you want (or as your ISP can deliver) without being billed for it. Peering arrangements and large corporate connections have been billed this way for decades without issue.
5% max allowable utilization is not "high" by any definition.
said by Wilsdom:Good luck with that.
I.e. a "cap" on Comcast's profit.
