As previously mentioned, the servers could go FIFA 23 Coins down intentionally or accidentally. Beginning at 7:30 a.m. UTC, all available services will go down for about an hour and a half as EA Sports will be updating its servers. This is routine maintenance, and users don't have to be worried about it.
However, there have been occasions of the past in which the servers went down without prior notice. This occurred during the early time period that was available for FIFA 23 and annoyed the majority of players. Therefore, it's crucial to be aware of when servers are down and there's more than one method to check.
The best option is that you join the official Twitter handle of FIFA Direct Communication. EA utilizes this handle to provide important information and make sure that there's no miscommunication between their players. If the game is unavailable for maintenance, the game will notify players using that Twitter handle.
Another option is to utilize the website Down Detector. This is a community-run resource site that tracks the server status for various sites and video games. In the event that FIFA 23 is not working it will be the top place for players to find out the status.
The third and least convenient method to determine this will occur directly through the games. When servers have gone down all functions of the Ultimate Team mode and others will be inaccessible. It's not the best method to determine this, as it could be due to buying FUT 23 Coins problems with the player's network.
