Nintendo has scheduled a new round of routine maintenance for its network servers. This maintenance period has been scheduled for the evening of December 5th, 2017 (which is next week at the time of this writing). Wii U and 3DS users won’t have to worry because this maintenance will only affect the Nintendo Switch’s network servers.
- DECEMBER 5th, 2017 – 4:50 PM to 6:30 PM (Pacific) / 7:50 to 9:30 PM (Eastern)
As per usual, Nintendo has stated this maintenance will affect “certain network services”, which will become unavailable while the work is being carried out. With that said, keep this time in mind if you intend to do any online matches on this day.
