Incident History
July 2026
DoS Attack
Started:
monitoring
We have deployed countermeasures and our servers are largely back to normal again. We keep monitoring the situation. If you encounter any issues please let us know!
investigating
We are continuing to investigate this issue.
investigating
We are experiencing what looks like a coordinated DoS attack against our API servers. We are monitoring the situation and are assessing our reaction. Crate downloads and dependency resolution through the sparse/git index should not be affected.
June 2026
crates.io slowness
Started:
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.
investigating
crates.io responses are unusually slow due to database issues, with occasional 500s due to database timeouts. We are investigating.
May 2026
Reverse dependency pages unavailable
Started:
monitoring
Reverse dependencies remain disabled, but the rest of crates.io is functioning normally.
identified
The reverse dependencies pages are temporarily unavailable. Other crates.io functionality should continue to function normally.
Degraded performance on crates.io
Started:
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.
April 2026
Git index slow to update
Started:
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.
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.
