Phone-PowerAccording to Phone Power, yesterday’s day long outage was caused by a massive cyber attack.

In an e-mail exchange with Consumer Press, a source at Phone Power told us that their network was attacked by an unknown source. He wrote that the data they have collected about the attack has been turned over to the FBI, and it is already under investigation by the agency. He declined to detail the nature of the attack.

Phone Power provides Voice Over Internet Protocol (VOIP) phone service to both residential and commercial customers. It is a privately owned company that was founded in 2005. The phone service is sold through their website and at Best Buy stores.

The outage began at approximately 10:30 AM Eastern time yesterday (May 2). Phone Power announced via Twitter that the phone service was restored at approximately 5 PM. For several hours afterwards, some users continued to report that their service was still not working.
