On Monday 1st June, Pokémon GO will experience downtime for a number of hours. If you're concerned about your app not working as it should or any issues with your account, don't worry - everything will be up and running again soon.
The game is planned to be down globally for seven hours, meaning you'll be unable to play it as you normally would during that time. Below, you can see when Pokémon GO is planned to be offline in your area, as well as when it will be back online (thanks, Eurogamer):
- UK: 7pm to 2am (BST)
- Europe: 8pm to 3am (CEST)
- US: 11am to 6pm (PDT) / 2pm to 9pm (EDT)
- Australia: 4am to 11am on Tuesday, 2nd June (AEST)
As for why Pokémon GO is down? Developer Niantic has said that the game is being taken offline for “server maintenance," going on to apologise for the inconvenience caused and confirming that the downtime will "have no impact on your account".
What Niantic specifically means by "server maintenance" is unknown, although it has been theorised that the developer may be transferring the game to new servers altogether.
