Today Nintendo has announced they will be taking the Nintendo eShop back down today starting at 4 pm EST until 4 am EST.
We sincerely apologize for the connection problems in the Nintendo eShop. We understand this is taking longer than expected, but we can assure you that providing a solution is our top priority. We are determined to make sure everyone can enjoy all that Wii U and Nintendo 3DS have to offer. In an effort to manage the high volume of traffic and ultimately improve your experience, we are temporarily taking the Nintendo eShop services offline between the hours of 4 p.m. – 4 a.m. ET. Thank you so much for your continued patience. We will keep you updated.
