Duo Security Status FAQ

Is Duo Security down right now?

The verdict at the top of this page comes from the latest poll of the official Duo Security status feed and refreshes automatically, so you are not looking at a stale cached answer. PulsAPI re-checks a vendor every 60 seconds whenever it is not fully operational, or has changed status in the last 30 minutes, so an incident is always on the fastest cadence. Vendors that are stable and rarely watched are re-checked every 5 to 20 minutes instead.

What should I do if Duo Security is not working?

Check the component list on this page first to see if your failure matches a known outage. If it does, you can report the issue for other engineers, follow the incident timeline for vendor updates, and run any fallback your app supports until Duo Security recovers.

How do I check Duo Security uptime history?

PulsAPI tracks Duo Security uptime over 30, 60, and 90-day rolling windows. The current 30-day uptime is 100.00%. The 90-day uptime strip on this page is public: no account needed. A free account adds alerts whenever Duo Security changes state, plus 15 days of incident detail; Pro extends that to 90 days and Business to 13 months.

How fast does PulsAPI detect Duo Security outages?

PulsAPI reads the official Duo Security status page. PulsAPI re-checks a vendor every 60 seconds whenever it is not fully operational, or has changed status in the last 30 minutes, so an incident is always on the fastest cadence. Vendors that are stable and rarely watched are re-checked every 5 to 20 minutes instead. Alerts reach Slack, Discord, Microsoft Teams, PagerDuty, or email within seconds of detection.

Does PulsAPI track individual Duo Security components?

Yes. PulsAPI monitors 766 individual Duo Security components, so you can see which service or region is affected instead of a generic "service degraded" banner.

Can I get alerts when Duo Security goes down?

Yes. Create a free account and subscribe to Duo Security: the free plan covers three services with unlimited email alerts and no monthly notification cap. Paid plans lift the monitor limit entirely (Pro and above do not meter how many vendors you watch) and route the same alerts into Slack, Discord, Microsoft Teams, PagerDuty and webhooks.

How do I report an issue with Duo Security to the community?

Click "Report an issue" at the top of this page, pick the issue type and severity, and optionally add your region and a short note. Reports are anonymous and help other engineers spot Duo Security problems early. Official status pages often lag real incidents by 10 to 20 minutes.

Is there a free way to monitor Duo Security?

Yes. The free plan covers 3 monitored services with unlimited email alerts, permanently, so Duo Security plus two more costs nothing. Every new account also opens with a 30-day Business trial (unlimited monitors, Slack alerts, SLA reporting) with no credit card.

Track Duo Security with the rest of your stack

2463+ vendors in one dashboard, and an email the moment any of them changes state. Three free, and no monitor limit at all from $29/mo, unlike the alternatives, which keep charging by the monitor.
