Summary

Elevated 429 errors pulling from maven central

Customers running jobs that pulled dependencies from Maven Central experienced elevated 429 (rate limit) errors. We have worked with Sonatype to allow list CircleCI's dedicated IP ranges. Customers using our IP ranges feature should no longer see Maven Central rate limits affect their jobs while we continue work to fully address the issue for all customers. Customers whose jobs failed during this window may rerun affected jobs. We thank you for your patience while our team worked on implementing a fix.
