PlayStation Network Asia is Back
Oh yes, it finally came back from a prolonged stupor ...
Yet, PlayStation Store (and online credit card transaction) is not available. It's a progress though, much better than "totally not available." Here is a news article yesterday about this (PSN service coming back in Asia tomorrow, Welcome Back package detailed - Joystiq).
Here is the link to a Google Translate page (caution: a flaky translation) of the announcement and apology from Sony (Japanese).
It seems hackers are expanding their activities against Sony worldwide, it's truly is "add insult to injury" for Japan considering the recent massive earthquake and tsunami.
