UPDATE: Activision reached out to Rectify Gaming saying The Nintendo Wi-Fi Connection service was discontinued being the reason for Call Of Duty becoming offline.

Here is the official statement:

“The Nintendo Wi-Fi Connection service, which provides certain online functionality for many Wii, Nintendo DS, and Nintendo DSi software titles, was discontinued.”

We initially thought the servers were taken down, but it was the Nintendo Wi-Fi Connection service that turned off.

Original: While Call of Duty servers have come back online for Xbox 360 games such as Black Ops 1, 2, and Modern Warfare 2, servers have become offline for the Nintendo Wii and DS. When trying to connect to any online Call of Duty title for the older Nintendo consoles you’ll receive an error.

Twitter user, @racerize shared images of Call of Duty: Modern Warfare Reflex, Black Ops and Modern Warfare III. 

Yes, in case you didn’t know the servers for these COD titles on Nintendo consoles were still online until now. If people were actually online is another story. Call of Duty hasn’t been on a Nintendo console since Call of Duty: Black Ops II on the Wii U. Microsoft signed an agreement with Nintendo to bring Call of Duty to their future console for the next 10 years once the Activision Acquisition goes through.

Nintendo’s next console is reported to come out in late 2024.
