Russian telecommunications regulator Roskomnadzor may have gone a tad overboard while complying with court order to block Telegram messenger in the country. 

In an attempt to block servers used to circumvent the ban, Roskomnadzor blacklisted several million addresses used by Google’s and Amazon’s cloud platforms, thus impacting plenty of unrelated services – including the Nintendo Network.

Russian users are sharing screenshots of online Nintendo games failing to connect on all of three platforms running Nintendo Network. Since it’s internet providers who are setting up the blacklists, the actual number of impacted services varies by carrier. However, it seems that software which uses peer-to-peer connections, like Splatoon 2 and The Legend of Zelda: Tri Force Heroes, are the most common victims of the outage - although some users are reporting that they cannot access the Nintendo eShop, too. 

On Nintendo Switch, running the network test may show the NAT type being degraded to F, which means connection to other consoles isn't possible. It is noted that the PlayStation Network seems to work as intended. Nintendo has acknowledged the outage on social media, but has no information to share at this time.

This is, unfortunately, not the first time Russian internet-controlling officials have accidentally blocked cloud services like AWS while trying to pin down something way more specific; we hope that Nintendo’s online services will return to normal operation soon.
