Possibly. I can't say because they've [Nintendo] left the Wii U and 3DS for dead for 5 years at this point. Might just be Pretendo working on their servers, though, if you're using their servers.

wdym? We need more information. Source, what this could mean. ect.

i love to be optimistic but honestly i don't think so, no, just keeping the last servers online still requires some updates from time to time, and the friend network on nintendo servers still isn't shut down, login and pokemon bank too so ig its just (sadly) that.
