There are several ways to determine if the FIFA 23 Coins servers are down
As mentioned above, the servers may go down in the course of a planned or accidentally. Starting at 7:30 a.m. UTC, all available services will go down for about an hour half since EA Sports will be updating its servers. This is normal maintenance, so players shouldn't be worried about it too much.
However, there have been instances when the servers were down without prior notification. This happened during the early acces period for FIFA 23 and irritated many players. This is why it's vital to be aware when the servers are down, and there's many ways to know.
The best option is for you to join official Twitter handles of FIFA Direct Communication. EA employs the handle to deliver important information and ensure that there's any miscommunication with their player base. If the game is unavailable for maintenance, they will update players through that Twitter handle.
Another option is using the website Down Detector. This is a user-generated resource site that keeps track of the server status of various sites and games. Should FIFA 23 is down the site will be one of the best places for players to look up the status.
The third and least convenient way to know directly from the game. If the servers go down, all features of that game, including the Ultimate Team mode and others are not available. It isn't the ideal way to find out, as this could also be due problems with the player's network.
Even if the servers are dead there are still some areas that are part of cheap FIFA 23 Coins will still be accessible. The offline game modes are playable as they don't rely on the internet to play. Some intriguing changes have been made to the careers mode for the current year's edition which allows players to join their favourite clubs to new glory.
