Docker Registry 5xx errors - 2019-09-27 03:30
Triggered #15192: Firing 1 - 5xx Error Rate on Docker Registry Load Balancers
GCS connection errors again:
gcs: Get https://storage.googleapis.com/gitlab-gprd-registry/docker/registry/v2/repositories/<redacted>/<redacted>/_manifests/tags/release/current/link: read tcp 10.222.9.4:42948->74.125.141.128:443: read: connection reset by peer
Had stopped occurring by the time we were alerted, but this is now two days in a row.
@gitlab-com/gl-infra FYI, this is a new thing that we might have to look out for. Twice in two days is co-incidence, and a third time would warrant looking much much harder into what's going on.
