Shared web hosting accounts are not capped. If you go over your limit(s) you will be charged the overage amount for that specific package. We will never shutdown your account if you go over your limits, regardless of the amount.
Dedicated servers on a 10Mbps connection are capped at 10Mbps. Any dedicated servers sold with 10Mbps or more are on a dedicated (to you) 100Mbps uplink. Overage is sold at a flat rate as shown during the ordering and checkout process.
