Last month, a single container in my GKE cluster (Sao Paulo region) entered an error loop, outputting to stdout at ~2k logs/second.

I discovered the hard way that GKE's default behavior is to ingest 100% of this into Cloud Logging with no rate limiting. My bill jumped nearly 1000% before alerts caught it.

Infrastructure (Compute): ~$140 (R$821 BRL) Cloud Logging: ~$1,300 (R$7,554 BRL)

Ratio: Logging cost 9.2x the actual servers.

I fixed the loop and paused the `_Default` sink immediately.

I opened a billing ticket requesting a "one-time courtesy adjustment" for a runaway resource—standard practice for first-time anomalies on AWS/Azure.

I have been rejected twice.

The latest response: "The team has declined the adjustment request due to our internal policies."

If you run GKE, the `_Default` sink in Log Router captures all container stdout/stderr.

There is NO DEFAULT CAP on ingestion volume which is an absurd!

A simple while(true); do echo "error"; done can bankrupt a small project.

Go to Logging -> Log Router. Edit _Default sink.

Add an exclusion filter: resource.type="k8s_container" severity=INFO (or exclude specific namespaces).

Has anyone successfully escalated a billing dispute past Tier 1 support recently?

It seems their policy is now to enforce full payment even on obvious runaway/accidental usage.
