It happened again that some of our deployments were rejected with 403 for a couple of days straight but then everything corrected itself again without intervention. We are running daily build and deploys to staging, so not all of these deployments are critical but one of these days it will happen that production hotfix will be impossible due to 403. What can I provide to help you troubleshoot?
