Both Sony's PlayStation Network and Nintendo's Eshop online services are currently suffering outages. The timing of these isn't ideal, given that it's Christmas day and many new PlayStation 4 and Nintendo Switch owners are likely trying to connect to the services to redeem or play games.

Sony has acknowledged the issues on Twitter, saying it is "aware that some users are having issues redeeming vouchers on PSN." However, reports from Twitter users trying to play their PS4s suggest the issues extend beyond just the ability to redeem vouchers, and that people are having trouble connecting to the online service as a whole.
