For a best appreciation of deployment impacts, we use a scale from 0 to 3 :
0 : not critical (no impact is expected after the deployment of the feature or fix, it's often related to the Fasterize website, API or auxiliary tools)
1 : minor (it may have a minor impact on optimized websites operations during the deployment, it's often related to the optimization engine or the cache layer)
2 : major (it may have a major impact on optimized websites. It is advisable to monitor the websites during this deployment).
