Two ways to reach Google when GCP is the problem. Use both — the channel gets attention fast, the case gets an SLA and a paper trail.
Slack
#plastic-gcp is a shared Slack Connect channel with our Google account reps. Good for
“is this a known issue”, quota bumps, pushing on a stalled case, and anything
where you want a human before you want a ticket. Ask a founder for an invite if
you’re not in it.
Support cases
File at console.cloud.google.com/support/cases. This is the only path that gets an SLA, so open a case for anything real — outages, billing disputes, quota increases, suspected platform bugs — even if you already asked in Slack. Include the project ID, the resource, and a UTC timestamp range; support will ask for all three otherwise.
