Based on the search results, there is no clear indication of what happened to Discord. The search results show that there have been some incidents of Discord being down or having issues, but these incidents have been resolved. There is also a post on Reddit from 2022 about the CSS being broken in the app, but it is unclear if this is related to any recent issues. It is possible that there have been other issues with Discord that are not reflected in the search results, but without more information, it is difficult to say what happened to Discord.
