How crates.io reports incidents

Not enough incidents to compare crates.io with other vendors yet: a vendor needs 20 incidents in a year and 10 with full update detail (crates.io has 8 and 48).

Provisional. Built nightly from every archived version of each incident, last on Oct 19. Compare all vendors

Dependencies

What crates.io relies on and who relies on crates.io, as observed in status-page incidents: who they blame, where they say they run, and who fails at the same time. Observed, not verified.

crates.io depends on

Provider	Evidence	Signal
GitHub	blamed in 2 incidents “…ishes The incident has been resolved. Crate publishes might be delayed due to the current GitHub outage. We're sorry for the disruption. The incident has been resolved. We are continuing to investigat…” incident	Strong
Heroku	blamed in 1 incident; together in 1 outage event “…crates.io. We're continuing to monitor the situation, and you can follow the progress on Heroku's status page: https://status.heroku.com/incidents/1973 This incident has been resolved.…” incident	Likely

Outage events: Microsoft Azure, Jan 25, 2023 (timing), AWS us-east-1, Dec 22, 2021 (timing), Heroku, Mar 16, 2020.

Strong: same company, or blamed in two separate outages. Likely: blamed once, or named as hosting and failing together. Weak: listed as a subprocessor, integration-only, or failing together repeatedly without being named.
