Topic: Error Code 121-1500

I just updated my 1 month old 3DSXL to its latest update and i cant access miiverse. I get the 121-1500 error code

How long has it been going on? Nintendo's diagnosis is just that Miiverse is down.

Well i have only been at it for about an hour .. Thats when i updated it. I can acess the web fine but not the e-shop or miiverse.

Is miiverse like a way to have achievements?

Miiverse is basically like a social network for the 3DS and Wii U. I would just try it later today, and it'll probably fix itself. If it still doesn't work, I'd call Nintendo.
