Incident History

June 2026
crates.io slowness
minor

Started: Jun 14, 1:20 AM

identified
The read-only replica database used for many of our common queries is under heavy load. We are evaluating options to deal with this.
Jun 14, 1:37 AM
investigating
crates.io responses are unusually slow due to database issues, with occasional 500s due to database timeouts. We are investigating.

Reverse dependency pages unavailable
minor

Started: May 23, 6:47 PM

monitoring
Reverse dependencies remain disabled, but the rest of crates.io is functioning normally.
May 23, 7:19 PM
identified
The reverse dependencies pages are temporarily unavailable. Other crates.io functionality should continue to function normally.

Degraded performance on crates.io

Started: May 20, 3:52 PM

monitoring
Crates.io is currently under a suspected denial of service effecting 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.

Git index slow to update
minor

Started: Apr 14, 8:48 PM

monitoring
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.
Apr 14, 9:08 PM
investigating
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.
