Update: No maintenance after all – More Wii U and 3DS maintenance happening later today

Update: Nintendo has now removed any mention of this upcoming maintenance from its official page. I suppose that means there won’t be any maintenance after all!

Nintendo completed several hours of maintenance for both Wii U and 3DS a short while ago. However, additional maintenance will be taking place in just a matter of hours.

Below is a breakdown of the different times:

6 PM PT (Monday) – 4 AM PT (Tuesday)
9 PM ET (Monday) – 7 AM ET (Tuesday)
2 AM in the UK (Tuesday) – 12 PM in the UK (Tuesday)
3 AM in Europe (Tuesday) – 1 PM in Europe (Tuesday)

This maintenance period will affect online play, rankings, and other Internet-related elements.
