- Even a very short authentication failure can trigger immediate outage perception because users cannot get into the product at all.
- The incident crossed several login surfaces rather than staying isolated to one app shell.
- This is one reason crowd reports can spike before anyone has time to diagnose whether the deeper issue is auth-only or platform-wide.
