Question 2

Accepted Answer

crates.io's last resolved incident started 15 days ago and lasted 1h 28m (a partial outage).

Question 3

What's crates.io's 30-day uptime?

Accepted Answer

crates.io's 30-day customer-perceived uptime is 99.990%. The figure is weighted (full-outage = 1.0, degraded = 0.3) so component blips don't collapse the score the way a raw incident-count would.

Question 4

How do I monitor crates.io in production?

Accepted Answer

Sign up to CheckUpstream and add crates.io to a watchlist. We send incident alerts via Slack, email, webhook, or PagerDuty within seconds of detection — covering both the official status page and community signals (HN, Reddit, Bluesky, Cloudflare Radar).

Question 5

How does CheckUpstream track crates.io?

Accepted Answer

We poll crates.io's official status page on a 1-5 minute cadence, parse its RSS / Atom feed as a fallback, ingest community signals from social platforms, and aggregate per-org SDK telemetry. Multiple sources reduce false positives versus any single feed alone.
