For me, it lasted part of the afternoon and all night, starting at about 3pm local time (my time zone is GMT + 9 hours) and by midnight the Akiba site was still being hijacked and I gave up trying.
The Akiba site started to open and after a second or two the Akiba site was then hijacked over to "http://friends.dormitory.com/1/welcome9.html" - pressing the browser's back button took you back to my home page (Google).
This morning from 4am, all is working fine again
