This topic provides FAQ about CU subscriptions.

When does a purchased CU subscription take effect?

A CU subscription takes effect 1 to 15 minutes after payment is successful. The lifecycle of the CU subscription begins only when the CU subscription takes effect.

After I purchase a CU subscription, how can I determine whether it has taken effect?

After you purchase a CU subscription, log on to the Function Compute console and go to the Resource Center page. In the Purchased Resources section, you can view your resources. The instances in this list have already taken effect. You can contact us to determine whether your CU subscription has taken effect. If the system cannot activate your CU subscription within 4 hours, you will receive a full refund. You can then purchase the CU subscription again.

When does a monthly or yearly CU subscription expire?

  • Monthly subscription: The lifecycle of the subscription is calculated in months. If you purchase a one-month subscription, your resources will expire the next month at 00:00:00 on the day following the day of the month on which you purchased the subscription.
    • Example 1: A new one-month subscription is purchased at 15:00:00 on August 14, 2020. In this case, the subscription expires at 00:00:00 on September 15, 2020. The lifecycle of the subscription is 31 days and 9 hours.
    • Example 2: A new two-month subscription is purchased at 15:00:00 on August 14, 2020. In this case, the subscription expires at 00:00:00 on October 15, 2020. The lifecycle of the subscription is 61 days and 9 hours.
    • Example 3: New one-month subscriptions are purchased at 15:00:00 on January 29, 30, and 31, 2020. In this case, all of these subscriptions expire at 00:00:00 on March 1, 2020.
  • Yearly subscription: If you purchase a one-year subscription, your resources will expire the next year at 00:00:00 on the day after the day on which you purchased the subscription.
    • Example 1: A new one-year subscription is purchased at 15:00:00 on August 14, 2020. In this case, the subscription expires at 00:00:00 on August 15, 2021. The lifecycle of the subscription is 366 days and 9 hours.
