Pokemon GO players are experiencing server issues, preventing them from logging into the game. The problem coincides with the start of the Hisuian Samurott Raid Day event, causing frustration among fans. The sudden spike in reports of login issues has left players wondering if the game is down for maintenance, despite no prior announcements of regular maintenance. Niantic Support has acknowledged the severe server issues and has offered additional time for the Hisuian Samurott Raid Day event as initial compensation. There are no known fixes for the issue, and players will have to wait for developers to resolve it. For those who have access to the game, guides for the Hisuian Samurott Raid and other December 2023 content are available for interested trainers.
