On November 22nd, 2020 we noticed random failures across our DockerHub infrastructure. This was caused by a failure to authenticate with DockerHub following the rollout of rate limiting (see here).
This presented with an error message similar to the following:
You have reached your pull rate limit. You may increase the limit by authenticating and upgrading...
We rolled out a fix to authenticate with our DockerHub organization.
This affected results collected between November 20th, 2020 and November 25th, 2020.
