Madden 23 down reports arise on October 6, attributed to EA shutting down servers for maintenance.
Madden 23 Maintenance Status:
According to EA’s announcement, they will be conducting maintenance on October 6th from 11:00 a.m. UTC to 3:00 p.m. UTC. Players will be unable to play online while they work on it, but management will return us to the game as soon as possible.
It’s not yet sure if a new update will be released along with this maintenance, but the official Madden NFL Twitter account did mention that the creators are looking into a solo battle issue.
