June 2 (Bloomberg) -- Sony Corp. fully resumed its PlayStation Network service today in the U.S. and Europe after a hacker attack six weeks ago led operations to be suspended.
The company has restored the network in all markets except Japan, Hong Kong and South Korea, Tokyo-based Sony said today. Users of its Qriocity entertainment services will be able to download music with the resumption, while video on demand will remain suspended until further notice, the maker of PlayStation game machines said.
Sony said May 31 that the services would be available before June 5 except in the three regions. The company, which estimates that the attack will cost about 14 billion yen ($173 million) this fiscal year, didn’t say today when it expects to restore the network in Hong Kong, Japan and South Korea.
The company said it improved security after the intrusion, which led to the theft of data on more than 100 million accounts. Sony increased the number of firewalls between servers and added software to monitor intrusions and system vulnerabilities before resuming partial services such as online gaming in the U.S. and Europe, it said May 15.
Sony fell 1.4 percent to 2,149 yen as of 2:18 p.m. in Tokyo trading. The benchmark Nikkei 225 Stock Average lost 1.6 percent.
