  1. 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.

    We are continuing to investigate this issue.

  3. monitoring Jul 11, 2026, 03:06 PM UTC

Minor June 14, 2026

crates.io slowness

Detected by Pingoru
Jun 14, 2026, 01:20 AM UTC
Resolved
Jun 14, 2026, 01:53 AM UTC
Duration
33m
Affected: crates.io
Timeline · 3 updates
  1. 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.

  2. 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.

  3. 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 April 14, 2026

Git index slow to update

Detected by Pingoru
Apr 14, 2026, 08:48 PM UTC
Resolved
Apr 14, 2026, 11:44 PM UTC
Duration
2h 56m
Affected: crates.io
Timeline · 3 updates
  1. 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.

  2. 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.

  3. resolved Apr 14, 2026, 11:44 PM UTC

    The indexes are now back to normal operations.
