Questions

How common are outages caused by storage?

11 incidents in the last 12 months across the vendors tracked here were traced to storage 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.

From vendors' own status pages and disclosures. Times as reported. Logos via logo.dev; trademarks belong to their owners.

Weekly: the week's major outages, postmortems and breaches, Saturday mornings.
