I've had instances on GCE hosting multiple websites for years. Suddenly, without any warning or notice, my instances went unreachable on 6/19.
After wasting several hours trying to debug this, I found that a [email protected]
service account was deleting firewall rules from my account! Even if I click "Enable HTTP/HTTPS traffic" when configuring the instance, a few minutes later the GCE enforcer deletes the rules again.
So many questions (and so frustrating!). What is GCE enforcer? Why is it deleting my firewall rules without permission or notice? How do I disable it?

rules. I can't find any documentation on it, nor any useful pointers online.
