Extend Capacity Blocks

With Capacity Blocks, you reserve compute capacity for your workloads, ensuring availability and consistency. To accommodate your changing needs, you can extend the duration of your existing Capacity Blocks as required.

To extend a Capacity Block, it must have a status of active or scheduled, and have no extensions that are payment-pending. You can request to extend the duration of your Capacity Block up to a minimum of 1 hour or a maximum of 56 days before it expires. You can extend your Capacity Block by 1-day increments up to 14 days, and 7-day increments up to 182 days (26 weeks) total. When you extend your Capacity Block, its end date will be updated so that your instances can continue to run without disruption.

Billing

The price of a Capacity Block offering is charged up front. The extension will remain in payment-pending until the bill is paid. If your payment can't be processed within 12 hours, or up to 35 minutes before the Capacity Block is scheduled to end (whichever comes first), your extension is not successful and the status changes to payment-failed. Your Capacity Block reservation will remain active and will be terminated on the original end date.

After your payment is processed successfully, the Capacity Block extension status changes to payment-succeeded and the end date of the Capacity Block reservation will be updated to the new end date. The details of your extension can be viewed in the Capacity Block Extension details section of the console, or by using the describe-capacity-block-extension-history command.
