## Updates from Harness
### 2026-06-17 13:42 UTC: investigating
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.

### 2026-06-17 14:03 UTC: identified
The issue has been identified and a fix is being implemented.

### 2026-06-17 14:21 UTC: monitoring
A fix has been implemented and we are monitoring the results.

### 2026-06-17 15:21 UTC: monitoring
Maven Central is rate-limiting requests originating from our us-central1 NAT egress IP. Other regions (us-west1, us-east5) are not affected. The Maven/Sonatype team has been engaged and is actively working on lifting the rate limit for our IP range.

### 2026-06-17 16:12 UTC: monitoring
We are continuing to monitor for any further issues.

### 2026-06-17 17:13 UTC: resolved
This incident has been resolved.
