There'll be an extra bit of Nintendo Network server maintenance this morning, but it's only scheduled for five more hours. Wii U and 3DS downtime regularly occurs between 1PM and 5PM PT (4PM to 8PM ET/9PM to 1AM UK time) every Monday, but today's maintenance begins early at 8AM PT (11AM ET, 4PM UK time). Some in-game and Miiverse features won't be accessible during the downtime, and disconnections from online games may occur.

Nintendo hasn't said what the extended maintenance is for; we wonder if we'll find out in tomorrow's Nintendo Direct, billed for Wii U and 3DS games due later this year.
