How long do Duo Security incidents last?

3.2 hmedian incident duration40 measured
10.7 h90th percentile1 in 10 ran longer
102 minmedian, major/critical only9 incidents

From 40 incidents with a vendor-posted start and resolve time. Longest on record: VoIP and SMS Delivery Issues in Israel — 4.1 days (2026-07-23 18:02 UTC). Excluded, never estimated: nothing. Duration is the gap between the vendor's own posted timestamps — it is not measured downtime, uptime or an SLA figure, and a vendor that posts every blip will look worse here than one that posts nothing. Same rule as the outage-duration dataset.
