Outage in Harness
Cloud builds are failing with 429 Too Many Requests error while downloading artifacts from central sonatype registry.
Resolved MinorIncident Report
Summary AI Generated
Harness CI cloud builds (Windows and Linux) failed for approximately 3.5 hours due to Maven Central rate-limiting (HTTP 429) requests originating from Harness's us-central1 NAT egress IPs, following new rate limits implemented by Sonatype. Builds in other regions (us-west1, us-east5) were unaffected. Harness engaged Sonatype to lift the rate limit on their IP range, and the incident was resolved within 3.5 hours.
We are investigating an issue affecting artifact downloads from Maven Central following recent rate-limiting changes implemented by Sonatype. Sonatype has recently implemented rate limits and builds downloading artifacts from central sonatype https://central.sonatype.org/faq/429-contact-support/. Customers downloading artifacts would be impacted.
We are actively engaging with Sonatype to mitigate the issue here.
