The Switch online launch will be preceded by a period of server maintenance, after which you'll be able to jump in, sign up for the service, and play some of the classic games being offered. > The Nintendo Support page says that the 6.0 update will go up at 5 PM PT / 8 PM ET, followed by a three hour maintenance period. Once the maintenance completes, around 8 PM PT / 11 PM ET, you can log on to purchase your Nintendo Switch Online membership, but you'll need to update to version 6.0 first.
