How do I determine if a Destiny 2 CAT error on PS5 is due to Bungie's servers being down or undergoing maintenance, rather than my own network or an update?

To differentiate between your network issues and Bungie's server problems, the most reliable approach is to check official Bungie communications. Visit help.bungie.net/en/Errors for a comprehensive list of error codes and their meanings. Follow @BungieHelp on Twitter for real-time updates on server status, maintenance, or widespread issues. Community forums (e.g., Reddit's r/DestinyTheGame) or services like DownDetector can also indicate if many other players are experiencing similar issues simultaneously, pointing to a server-side problem.
