Account suddenly downgraded from tier 3 to tier 1

Hello,

My Gemini API access was automatically downgraded from Tier 3 to Tier 1 without any action on my part or prior warning. This is now causing production-level outages. I am on a postpaid account that had no billing issues or unpaid invoices. I added some funds manually to go into prepaid mode, which changed my tier status to tier 3 again.

Additional context:

  • My project was on Tier 3 for some months
  • I was downgraded automatically to Tier 1 with no notification
  • No billing issues or unpaid invoices.

What I’m requesting:

  • Immediate restoration of Tier 3 access given active billing and stable prior usage
  • Clarification on why the automatic downgrade occurred
