We like to think of FASTnet as a family and we’d like you to help our family grow! As a FASTnet customer, you can earn a $25 bill credit for every new customer you refer. 

Just make sure that any new customer you send our way knows your name and phone number—and that they give it to us when they sign up for service. For every new customer you refer that gets installed, we’ll put a $25 credit on your bill. So help us spread the word about FASTnet and earn a little money while you do it.
