Netflix customers going through DVD-withdrawal can breathe a sigh of relief as the online movie rental service said unspecified shipping problems have been fixed as of Friday.

“We are full systems go," said Netflix (NFLX) spokesman Steve Swasey, who declined to explain what the problem was. "We are safeguarding against it happening again."

As a result of the outage, Netflix will give a 15% discount to all impacted customers in their next bill. The company will also give individuals using the service on a free trial basis an extra week. 

“It was our mistake and we are going to make right with our members," said Swasey. 

Customers began complaining on Tuesday when Netflix suffered a full outage. The company, which serves more than 8 million customers, was only partially able to send out DVDs on Wednesday and Thursday. 

It was just the second time in Netflix's 11-year history that it wasn't able to ship movies. The other incident occurred in March and was based on an unrelated problem, Swasey said. 

Netflix sent out personal e-mails to those customers who were impacted, Swasey said.
