After the announcement last week that Nintendo was shutting down Miiverse, the company quietly announced that they are also discontinuing support for SplatNet.
SplatNet is an online service where you can check current and upcoming battle stages in Splatoon, check your current equipment and stats, see where you rank among your friends, as well as tweet out battle plans.
As of September 30th the service will end. There won’t be any change to the Splatoon game itself however. This also doesn’t affect the Nintendo Switch Splatoon 2 which doesn’t make use of SplatNet but instead uses SplatNet 2 in the Nintendo Switch app.
