Some customers are seeing very slow response times when working with GCR images through the replicated registry proxy. This is occasionally causing timeouts for requests.

We have begun taking steps to ensure our registry proxy infrastructure is provisioned with enough resources to field all it's requests without delay. We thank you for your patience while we work through this.
