Major July 11, 2026 DoS Attack 1h 19m crates.io
Started Jul 11, 2026, 02:22 PM UTC· resolved Jul 11, 2026, 03:42 PM UTC
- investigating Jul 11, 2026, 02:22 PM UTC
We are experience 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.
- investigating Jul 11, 2026, 02:22 PM UTC
We are continuing to investigate this issue.
- monitoring Jul 11, 2026, 03:06 PM UTC
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!
- resolved Jul 11, 2026, 03:42 PM UTC
This incident has been resolved. Big thanks to Fastly for providing their CDN services and their fast response time!
Minor June 14, 2026 crates.io slowness 33m crates.io
Started Jun 14, 2026, 01:20 AM UTC· resolved Jun 14, 2026, 01:53 AM UTC
- investigating Jun 14, 2026, 01:20 AM UTC
crates.io responses are unusually slow due to database issues, with occasional 500s due to database timeouts. We are investigating.
- identified Jun 14, 2026, 01:37 AM UTC
The read-only replica database used for many of our common queries is under heavy load. We are evaluating options to deal with this.
- resolved Jun 14, 2026, 01:53 AM UTC
The primary source of the load appears to have been a scraper abusing our API. We have blocked the scraper and the replica database has returned to its normal heavily loaded state instead of being overloaded.
Minor May 23, 2026 Reverse dependency pages unavailable 2d 22h crates.io
Started May 23, 2026, 06:47 PM UTC· resolved May 26, 2026, 05:00 PM UTC

Reverse dependencies remain disabled, but the rest of crates.io is functioning normally.
- resolved May 26, 2026, 05:00 PM UTC

- monitoring May 20, 2026, 03:52 PM UTC
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.
Minor April 14, 2026 Git index slow to update 2h 56m crates.io
Started Apr 14, 2026, 08:48 PM UTC· resolved Apr 14, 2026, 11:44 PM UTC
- investigating Apr 14, 2026, 08:48 PM UTC
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.
- monitoring Apr 14, 2026, 09:08 PM UTC
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.
- resolved Apr 14, 2026, 11:44 PM UTC
The indexes are now back to normal operations.
Minor September 2, 2025 Sparse Index CDN Invalidations Slow to Update 44m crates.io

- monitoring Sep 02, 2025, 10:48 PM UTC
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.
- monitoring Sep 02, 2025, 11:08 PM UTC
The sparse index has synchronized and is now up-to-date. CDN updates are still processing.
- monitoring Sep 02, 2025, 11:32 PM UTC
The backlog has cleared and all queues are nominal.
- resolved Sep 02, 2025, 11:33 PM UTC
