Some applications are having troubles being monitored by our systems and get redeployed with the Monitoring/Unreachable reason even though they are still available. We are investigating the cause of the issue.
EDIT 15:55 UTC: The cause has been found. This issue only affects applications tied to a unique IP proxy service. The issue has been mitigated in the last minutes and we are working to fully fix it.
EDIT 16:20 UTC: The issue has been fixed and should not happen again. If you encounter weird Monitoring/Unreachable deployments, feel free to contact our support team.
