We are continuing to investigate a network issue with a storage server in our US West region since around 14:50 UTC on July 6\. Customers may experience slowness in US West. We are working with our upstream network provider on a fix and will post updates here.

We are running a maintenance operation on our cache storage cluster to resolve the degradation. For roughly 15 to 20 minutes, caching will fall back to the GitHub Actions cache and may be slower; jobs will otherwise run normally. We will update once complete.
