This is getting ridiculous. Really makes me wonder what's going on behind the scenes, since, based on what we've seen, the online services for games really should require little to no integration work for the new account stuff. Maybe some new authentication stuff, but even that may not be necessary with NNID sticking around.

 

[L~A]

It may be getting ridiculous, but it's far from over My guess is large scale server upgrade or something.

Probably preparing for worldwide nintendo account launch coming up?

Nah, L~A is probably right that they're doing massive server upgrades/migrations right now. The new account stuff shouldn't have a huge impact on online play for Wii U and 3DS games.

Well, whatever it is, it's faaar from over, ha ha.

[Regiruler]

So THAT's why I haven't been able to play badge arcade past 12.

 

[L~A]

Hmm... I don't think so. Maintenance for Nintendo Badge Arcade is always specifically mentioned on the page.

 

[Pokemaniac]

Hmm... I don't think so. Maintenance for Nintendo Badge Arcade is always specifically mentioned on the page.

It could have been under one of the "certain network services" ones. Those seem to just be maintenance that's not targeted at a specific game.

 

[Regiruler]

Wait, no, my internet was just crud.

 

[L~A]

It could have been under one of the "certain network services" ones. Those seem to just be maintenance that's not targeted at a specific game.

Those "certain network services" maintenance are just the maintenance for the various Wii U / 3D games (third-party games) that Nintendo doesn't want to list anymore.

All Nintendo games get a separate listing no matter how trivial the maintenance is.

Talking of Nintendo Badge Arcade....

I've had Splatoon say it was under maintenance during one of the "certain network services" ones. Nintendo games definitely can be included.

 

[L~A]

Actually, that Splatoon maintenance was announced beforehand (but maintenance page wasn't update).

Pretty much the only time I saw them forget to mention it.

 

[Sagitario]

Anyone has been getting 118-0502 and 118-0516 errors since the maintenance on February 12th? It has been impossible to me to play online since then.
Wii U and 3DS games give me those errors while match-making (the consoles do connect to the Nintendo Network and eShop, though).

 

[Pokemaniac]

Actually, that Splatoon maintenance was announced beforehand (but maintenance page wasn't update).

Pretty much the only time I saw them forget to mention it.

Still, back when they were still listing each game individually, Nintendo games were often included.

Is there any maintenance due to the launch of My Nintendo in the West tomorrow?

Nope. Why would there be though? Service hasn't launched yet, and all necessary technical modifications and stuff have been done beforehand (like NoE's website updated for web eShop).

Launch should be pretty smooth.
