Wii U and 3DS eShop maintenance scheduled for tomorrow

The Wii U and 3DS eShops will both be affected by maintenance tomorrow. Between 4 PM and 6 PM ET (1 PM and 3 PM PT), users will be unable to access the two stores.

Also, we should mention that the June 1 maintenance that had previously been scheduled is no longer planned – at least as far as we know. It’s no longer listed on Nintendo’s maintenance page.
