Gamers won't be able to make digital purchases from Nintendo's Russian eShop for now. The gaming giant has announced that the eShop in Russia has been temporarily placed in maintenance mode "due to the fact that the payment service [it uses] has suspended the processing of payments in rubles." As Nintendo Life notes, people have been reporting about the outage on social networks, showing photos of their Switch getting error code 2813-0999 when they try to access the Russian eShop.
It's unclear if Nintendo itself cut off payments in the region on purpose, or if the company had no choice but to place the eShop in maintenance mode because a third-party processor removed ruble payments from its system. The translated wording seems to indicate that the latter is more likely.
Other gaming companies had previously taken steps to limit access to their products and services in Russia. CD Projekt Red halted sales of its games, including Cyberpunk 2077 and The Witcher 3: Wild Hunt, and all titles on its GOG store in Russia and Belarus. EA followed suit, preventing players in the two countries from making purchases from its Origin storefront and app.
Microsoft suspended all new sales of its products and services (including Xbox) in Russia, following a request from Ukraine to ban all players in the country from its system. Ukraine also asked Sony to ban all players in Russia from the PlayStation network, but the company has yet to respond. According to Eurogamer, though, Sony quietly pulled Gran Turismo 7 from sale in the country.
