GeoCities Japan: It’s the GeoCities closure all over again… The Japanese version will shut down at the end of March 2019. There will undoubtedly be older Japanese Poser and DAZ sites in there, and other useful digital graphics stuff, so you may want to do some personal archiving of such sites with the likes of Teleport Pro or WinHTTrack.
However, the digital superheroes of the Archive Team are on the case, and have so far saved 96 million URLs from GeoCities Japan. Presumably they’ve also grabbed the .ZIP files.
