How long do GitBook incidents last?

2.2 hmedian incident duration14 measured

22.2 h90th percentile1 in 10 ran longer

108 minmedian, major/critical only12 incidents

From 14 incidents with a vendor-posted start and resolve time. Longest on record: All AI based features including GitBook Assistant or AI search are failing with "something went wrong" — 27.0 h (2025-09-16 07:07 UTC). Excluded, never estimated: 1 resolved before started (vendor data error). 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.
