A subdomain pointing at nothing
One shop.example subdomain still has a CNAME to a cloud app that was deleted. Find it before someone else registers the name and serves content under your domain.
Briefing
Marketing ran a spring promotion on a hosted web app and then deleted the app. Nobody removed the DNS record.
A CNAME that points at a name which no longer exists is called dangling. If the cloud provider lets anyone claim that app name, they can serve pages on your subdomain. Check every name in the inventory with dig.
