Overview
- Users across Mexican cities reported service problems on Sunday, September 20, with Downdetector logging about 748 reports for Facebook and roughly 326 for Instagram.
- Facebook failures were split across types of access with about 49% reporting website access problems, 23% reporting server connection issues, and 15% reporting app errors.
- Affected users described feeds that would not update, trouble loading content, sudden logouts, and difficulties publishing photos and videos.
- News coverage and user posts on X amplified the scope of the disruption but did not find a confirmed technical cause or a public statement from Meta.
- Downdetector aggregates user-submitted problem reports and is used as an early outage indicator, though its counts reflect reports rather than a full measure of all affected accounts and some regions reported partial restoration later in the evening.
