Hackers have taken down the Sony PlayStation network this weekend in what is known as a distributed denial of service attack (DDoS), but service is back up now.

Although cyber-attacks overloaded the network and disrupted service, the company assured users that no personal information was compromised.

"Like other major networks around the world, the PlayStation Network and Sony Entertainment Network have been impacted by an attempt to overwhelm our network with artificially high traffic," Sony explained in a blog post. "Although this has impacted your ability to access our network and enjoy our services, no personal information has been accessed."

"We have seen no evidence of any unauthorised access to users' personal information," the company further reiterated in an update to the original post.

In light of the attack, however, Sony canceled the regularly scheduled maintenance, which was supposed to take place on Monday, Aug. 25. The company has yet to offer details for when it will reschedule the maintenance.

In addition to the DDoS attack on Sony's PlayStation network, attackers also diverted an American Airlines flight with a bomb scare. The flight in question carried Sony Online Entertainment President John Smedley, who was traveling in San Diego but wound up to Phoenix, Arizona instead, after the diversion.

The group that claimed responsibility for the DDoS attack that took down the Sony PlayStation network also suggested that there was a security threat to the flight. Sony said that the FBI is currently investigating the security scare that diverted the flight. Smedley reckoned that his trip took an unexpected turn, but refused to comment more on the matter.

The hackers behind the PlayStation attack said they also targeted Blizzard Entertainment and threatened to attack Microsoft's Xbox Live network as well. According to Reuters, the unidentified hackers said the purpose of their attack was to get Sony to spend more money on security.

As previously mentioned, the Sony PlayStation network is now up and running again, with no data compromised, but the routine maintenance is yet to be rescheduled. The company apologized for the inconvenience caused by this DDoS attack and promised to provide more details shortly regarding the upcoming maintenance.
