As a result, requests could be buffered while new instances are started, causing "cold starts", even for functions/containers with min_scale set to 1. Functions/containers with no running instances won't be impacted. - 5xx errors while calling functions/containers. As we restart system components to perform the upgrade, some in-flight requests (especially long-running ones) might be terminated before completion. Users mi
