Nintendo has begun replacing Wii units corrupted by fatal error 110213. An unknown percentage of users have been struck with the malfunction after attempting to download the WiiConnect24 update. Affected units will not be able to connect to Nintendo's online services and must be replaced.
Luckily, offline modes still function, giving you an opportunity to back up your Zelda progress onto SD before shipping the unit off to Nintendo's scrap yard. You do have an SD card, right?
