Timelines for new CUD model migration

Effective dates

The changes take effect on the following dates, depending on which scenario applies to you.

Customers who opt in early will be unable to purchase new spend-based CUDs for a few hours during their account migration. Google Cloud displays a warning about this outage in the Billing section of the Google Cloud console.

For customers who don't opt in early, the same outage occurs when they are automatically migrated to the new model in January 2026.

New customers

If you create a Billing Account on or after July 15, 2025, the new billing model applies to you for spend-based CUDs in the affected CUDs list.

For Billing accounts with any active spend-based CUDs in this list on or after July 15, 2024, the new model applies on January 21, 2026 at midnight US and Canadian Pacific Time (UTC-8). You can opt in earlier, starting July 15, 2025. In that case, the new model applies when you click opt-in. Learn more about how to opt in.
