First Signs of Life on PSN?

Taking a quick look on the Japanese PlayStation web pages via my PSP, I noticed the first upload since 28 April, a new PS3 video for some odd Japanese title, which one isn't really important. As its the first upload in almost a fortnight, is Japan getting ready to reactivate the PSN?

Hopefully we'll know soon enough, Anyone got a Jap PSN account to check - there is no sign of life on the European PSN at the moment. Logic would suggest that Sony will upload a range of test files over time to test the new system's function before relaunching, as this site links to Japan's PSN it could be a place to watch.
