Is Cisco Duo down for everyone or just me?

To determine whether it's a widespread Cisco Duo outage or a problem specific to your account or location:

1. Check the status indicator above — if this page shows a major outage, it's confirmed global.
2. Try a different device or network — if it works on mobile data but not Wi-Fi, it's likely a local network issue, not Cisco Duo.
3. Clear cache and cookies — browser issues can mimic service outages.
4. Check community reports — Downdetector and social media will show whether hundreds of other users are reporting the same issue.
5. Test the API directly (for developers) — a raw request returning 5xx errors confirms a service-side outage; a 429 means you've hit your personal rate limit.
