[URGENT] Production down - Tier 2 to Tier 1 auto-downgrade (known recurring billing sync bug)

Hi team,

My production app’s billing account was automatically downgraded from Tier 2 to Tier 1 on Aug 19-20, causing “You’ve reached the billing account tier cap and service has been paused” errors. This is blocking real, active users right now.

I have an active billing account, sufficient available credit, and a manually configured spend cap - so this is not a payment/credit issue. The usage spike that triggered this was organic growth (~10,000 new users), not fraudulent activity.

I’ve already opened a support case (#74646206) and submitted the official Billing Cap Increase form, but the review timeline is 24-48 hours, which is a long time for an active production outage.

I’ve also found that this appears to be a known, recurring issue affecting other developers - I found multiple similar reports on this forum:

  • “Recurring Bug: Account Abruptly Downgraded from Tier 3 to Tier 1”
  • “Usage Tier unexpectedly downgraded to Tier 1 and won’t update after payment”
  • “Auto-downgraded Tier 2 → Tier 1, billing active, no form response”

Could someone from the Google AI team please take a look at my account (details available via case #74646206) and help expedite a manual restoration?

Support Case: #74646206

Thank you.
