Questions
How common are outages caused by deployment or rollout?
37 incidents in the last 12 months across the vendors tracked here were traced to deployment or rollout in the vendors' own words.
How is this cause identified?
From the sentences where the vendor explains why the incident happened, or by hand for landmark postmortems. Symptoms like "elevated error rates" are never counted as a cause.
