The Nintendo Wi-Fi Connection
(WFC) service was an online gaming service

- Second week of November 2019
During the second week of November 2019 (11th to 17th),
Wiimmfi and Wii-Homebrew.com will be moved to a new server.

It is recommended not to schedule any tournaments during
that time as you might get kicked without notice.
