Short answer: With Web hosting, there is no such thing as “unlimited” and we’d rather be honest and state this up front than mislead you with claims of limitless resources.
Long Answer: Some Web hosts claim to offer “unlimited” plans with no set quota on bandwidth or disk space usage. The theory is to let you the customer use as many resources in the space as you want, and to load the space up with dozens or hundreds of Web sites if you wish.
The truth is that there is no such thing as “unlimited”. Claiming so is not only unsustainable from the perspective of the host being able to support such a setup, but also misleading advertising in that it implies customers can have something they truly cannot.
“Unlimited” plans are achieved through overselling, the process of reselling the same space and bandwidth to multiple customers. If you read the fine print of the average “oversell” Web host’s Terms of Service, you will find there is in fact a limit on the number of files, or the maximum data transfer rate you can use, which in and of themselves are more limiting than if you hosted with a “no-oversell” provider like Canvas Dreams.
We do place limits on the amount of storage space you can use and the amount of bandwidth allotted to your plan. We do this so we can guarantee accessibility and reliability of your account and ensure no other customer can “overrun” into your space and harm the performance of your Web site(s). However, the space and bandwidth in our plans is extremely generous and 99% of our customers will never go over. If you find you are approaching your quota we will notify you and suggest upgrading you to the next plan level up — and that’s all there is to it. No hassle, no complicated Terms of Service, just good, honest, sustainably provided Web hosting you can count on!
