Nintendo DSi Shop & Wii Shop Channel quietly pulled offline, with no ability to redownload titles
If Nintendo announcing the discontinuation of the eShop for the Nintendo 3DS and Wii U wasn't bad enough, strap yourselves in. Around 10:00pm CST, with no prior announcement, both the DSi Shop and Wii Shop Channels were quietly pulled offline, leaving previously downloaded purchases and titles unable to be redownloaded, showing error codes 290502 and 209601 for both systems respectively. Nintendo's CDN, which is the download server that houses all of the update and shop data, remains to be active with the ability to download titles with tools such as NUSDownloader, showing that only the frontend of the stores have suddenly disappeared. Nintendo's status page still lists that everything is operational, though it's currently unknown if this was a mistake like last year's eShop incident, or if this really is the end of an era.
