Immediate GCP DNS Outage Fix

My production site is suddenly unreachable; every DNS checker returns “DNS record not found.” The domain itself is registered and fully managed inside Google Cloud Platform, and the web tier runs on a VM with Cloud SQL in the back-end—no load balancer or recent configuration changes on my side. Something in Cloud DNS or the networking layer clearly broke and I need it repaired now, before downtime stretches any further.

What I expect from you today:
• jump straight into the project the moment access is shared,
• trace the missing or corrupted Cloud DNS records, correct them, and trigger proper propagation,
• verify that the VM, Cloud SQL connection, and any firewall or VPC rules align so traffic actually reaches the instance,
• bring the public site back online and confirm it resolves worldwide,
• outline the root cause and propose a brief, practical prevention plan so this outage does not recur.

I will give you full console access to the GCP project and the registrar panel. Because no prior changes were made, a fresh set of expert eyes is essential. If you have handled urgent Cloud DNS recoveries before and can complete the fix within a few hours, let’s begin immediately.
