It hasn't been the best week for Sony. After shutting down the PlayStation Network Wednesday night with no explanation, the company admitted late Friday that it had suspended the PlayStation 3 and PSP's online service due to an "external intrusion." The company did not elaborate, but it did say it would offer an update on the situation soon.

　　Sony is working "around the clock" to fix the PSN outage.

　　That update came late Saturday, when Sony Computer Entertainment America senior director of corporate communications and social media Patrick Seybold made a post on the official PlayStation Blog.

　　"We sincerely regret that PlayStation Network and Qriocity services have been suspended, and we are working around the clock to bring them both back online," he said. "Our efforts to resolve this matter involve re-building our system to further strengthen our network infrastructure. Though this task is time-consuming, we decided it was worth the time necessary to provide the system with additional security."

　　Sony then thanked the public for its patience but did not give an estimate as to when the PSN would come back online.
