What the data shows
Computed from every record, as of 2026-10.
- Claude reported 398 incidents in the last 12 months against 282 in the 12 months before: up 41%.
- 143 of the last 398 were marked major or critical, which is 36%.
- More reported incidents can mean more failures, more products or more honest reporting. These numbers cannot separate them.

Limitations
- Incidents are self-reported, so a company that reports more honestly can look worse.
- New products add new ways to have an incident, so counts can rise without reliability getting worse.
- Claude is much younger than GitHub, so its early years are not comparable.
