My Web hosting company, Dreamhost started a new marketing concept: Reduce the resource offered to new customer in order to better serve old customer and to increase reputation. This decision is anounce on their blog:

Every day, starting tomorrow, the amount of starting disk and bandwidth we offer new customers (this does not affect existing customers at all!) will drop. You can see the amounts here.

It’s a new marketing concept, as usually for hosting company and ISP new customers are kings.
