There were 4 crates.io outages since August 12, 2025 totaling 74h 58m of downtime. Each is summarised below — incident details, duration, and resolution information.
The reverse dependencies pages are temporarily unavailable. Other crates.io functionality should continue to function normally.
Reverse dependencies remain disabled, but the rest of crates.io is functioning normally.
This incident has been resolved.
Crates.io is currently affected by a suspected denial of service affecting the web frontend. The reverse dependency endpoint has been disabled. You will not be able to browse reverse dependencies on crates.io for the duration of the incident. All other operations, publishes and the index are operating normally.
All endpoints are now operational and available again.
The crates.io background worker is having a bad morning, and a backlog of Git index updates has accumulated. We have given the worker some coffee and it's catching up, but index updates for newly-published crates are running about an hour behind right now. The sparse index (used by default by all modern Rust versions) is unaffected.
The background worker has been told to get itself together. The queue is now trending downwards, but git index updates are still running an hour behind. We are continuing to monitor, but we expect this to resolve over the next few hours.
The indexes are now back to normal operations.
A backlog of CDN invalidations is causing a backlog of approximately 350 crate backlog for sparse index updates and CDN updates. We are monitoring as the queue is worked through.
The sparse index has synchronized and is now up-to-date. CDN updates are still processing.
The backlog has cleared and all queues are nominal.
This incident has been resolved.
