It's pretty straightforward: Customers who use Yahoo! Web Hosting can obtain unlimited disk space, data transfer, and email storage if they use their services consistently with the Terms of Service and these paragraphs.
What is appropriate usage?
Yahoo! Web Hosting is designed to serve the web hosting needs of small, independently owned and operated businesses in the United States. It is not appropriate to use our services to support large enterprises or internationally based businesses with a sustained demand that places undue burden on our systems or negatively impacts use by small, independently owned and operated businesses.
Yahoo! Web Hosting is a shared web hosting service, which means that a number of customers' web sites and other email or storage services are hosted from the same server. Yahoo! uses abuse controls to help ensure that use of our services does not adversely affect the performance of our system or other customers' sites. It is not appropriate to use an account primarily as an online storage space or for archiving electronic files. Disk space:
If you use your services consistently with the Terms of Service and these paragraphs, your site can grow as large as necessary to meet your small business needs, but to ensure a great experience for all, we will place some constraints on how fast you can grow. The vast majority of our customers' sites grow at rates well within our rules, but our abuse controls may cause a brief delay while we evaluate if expansion is appropriate. Data transfer:
In most cases, if you use our services consistently with the Terms of Service and these paragraphs, visitors to your web site will be able to download and view as much content from your site as they like. However, in certain circumstances, our server processing power, server memory, or abuse controls could limit downloads from your site.
You can also upload as much as content as you like each month, subject only to the Terms of Service and the rules that control how fast your site can grow (see above).Email storage:
You do not have to worry about hitting a storage limit if you use our services consistently with the Terms of Service and these paragraphs. Yahoo! will increase your space along with your appropriate small business needs, but our abuse controls may impact the rate of growth or your folder size, and there may be a short delay while we assess your usage. In some cases, creating additional folders or subfolders will help ensure that the system works well for everyone.
