What is Overselling and what is the Dangers Of Overselling Hosting Resources?
Overselling means that resources are being stretched to the limit and beyond. In other words what is going on is overselling. Overselling for a host is when they get more clients whose requirements exceed the available resources.
The disadvantages of overselling web hosting is that client sites take much longer to load. Many times they will be inaccessible altogether, resulting in a classic case to illustrate why cheaper can often be much more expensive.
