The outage of Sony's PlayStation Network ran into its sixth day Monday as the company said it has no timeframe for restoring the Internet-based system that links users in live game play worldwide.

In a blog post Monday, Sony spokesman Patrick Seybold said he couldn't predict when rebuilding work would be completed, but that it's a "time intensive process."

The company said on Thursday that it would take a "full day or two" to restore service after it first shut down the system that serves both PlayStations and its Qriocity entertainment services the previous day.

"An external intrusion on our system has affected our PlayStation Network and Qriocity services. In order to conduct a thorough investigation and to verify the smooth and secure operation of our network services going forward, we turned off PlayStation Network & Qriocity services on the evening of Wednesday, April 20th. Providing quality entertainment services to our customers and partners is our utmost priority. We are doing all we can to resolve this situation quickly, and we once again thank you for your patience. We will continue to update you promptly as we have additional information to share," Sony's Patrick Seybold had said late last week.
