Root Cause Analysis

DockerHub Image Pull Limits

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.
