User getting timeout while pushing to registry.gitlab.com

A GitLab.com is getting the following error sporadically while pushing a new image from a CI runner. It seems an odd endpoint to receive that timeout. The only thing I can think of is that this happened during a deploy, but they say they had to retry some builds several times to get it to work. Any ideas?

docker login -u gitlab-ci-token -p $CI_BUILD_TOKEN registry.gitlab.com 
Error response from daemon: Get https://registry.gitlab.com/v2/: Get https://gitlab.com/jwt/auth?account=gitlab-ci-token&client_id=docker&offline_token=true&service=container_registry: net/http: request canceled (Client.Timeout exceeded while awaiting headers) (Client.Timeout exceeded while awaiting headers)
