Nintendo has scheduled some routine network maintenance for the Switch and 3DS. This maintenance is going to affect the online multiplayer servers of “some software”, although Nintendo does not specify exactly what games this includes. So, if you have trouble performing matchmaking in any online-enabled game in particular, it could be due to this maintenance session.
Here’s the rundown of when the work will be carried out:
- Switch (Only) – November 5 @ 11:50 PM to 1:30 AM (Nov. 6) [Pacific] / 2:50 AM to 4:30 AM [Eastern]
- Switch and 3DS – November 6 @ 4:50 PM to 6:30 PM [Pacific] / 7:50 PM to 9:30 PM [Eastern]
As long as you avoid these time slots, you’ll be able to play without any interruption.
