Wii and DSI online digital stores have been dropped for several days. This fact has occurred without prior notice of Nintendo and the reason is not known (either a closure for maintenance or that they have stopped supporting it definitively), and from Eurogamer United Kingdom aim that they are inaccessible from, at least, the Past March 16.
Until this incident occurred, users could not buy new games at the Nintendo DSI store or in the Wii store channel, but they had available the titles they already had property.
As they explain in VGC, when opening the Wii Store, Error 209601 appears (with a message “could not be connected to the server”), while when trying to access DSI, we can see the 209502 error, which Indicates «Interference in the wireless connection». However, from GBatemp aim that the main server continues active, because games can still be downloaded through third-party tools.
At the moment, Nintendo has not pronounced itself about it.
