When a subscription instance expires, the services it provides may be affected. If you want to continue to use the instance, you must renew it within the specified period. Otherwise, instance resources such as vCPUs, memory, and disks are released and their stored data is lost permanently. This topic describes the renewal feature of ECS instances.
Overview
The renewal feature is applicable only to subscription ECS instances. Pay-as-you-go instances do not need to be renewed, but you must make sure that you have sufficient balance in your linked bank card, PayPal, or Paytm (India) account to cover the related costs.
If you renew an instance before it expires, the instance continues to work normally and retains all of its resources. For information about the status of a subscription instance after it expires, see Subscription.

Applicable timeframe | Renewal method | Scenario | Result |
---|---|---|---|
Before the instance expires | Manual renewal | You only renew the instance and do not change its configurations. | The new billing cycle starts from the original expiration date. |
Auto-renewal | You only renew the instance and do not change its configurations. The renewal operation is performed by the system based on your settings to ensure your business availability. | ||
Within 15 days before the instance expires | Renewal and configuration downgrade | You can renew the instance and downgrade its configurations. For example, you can downgrade the instance type, modify the public bandwidth configurations, or change the billing method of data disks. | |
After the instance expires but before the instance is automatically released | Renewal and configuration downgrade | You can renew the instance and change its configurations. For example, you can modify the public bandwidth configurations or change the billing method of data disks. | The new billing cycle starts from the day of renewal. |
Manual renewal | You only renew the instance and do not change its configurations. | The new billing cycle starts from the day of renewal.
Note If you enable the auto-renewal feature for an instance, the instance remains in the
Running state within 15 days after the instance expires. If you manually renew the
instance during this period, the new billing cycle starts from the original expiration
date.

Manual renewal
When you manually renew an instance, you can extend its expiration date but cannot modify its configurations. Only the base public bandwidth of the instance is renewed. The temporarily upgraded public bandwidth is not renewed.
- When you manually renew an instance that is in the Running state, the new billing cycle starts from the original expiration date.
- When you manually renew an instance that has expired, the new billing cycle starts from the day of renewal.
- One month, two months, three months, four months, five months, six months, seven months, eight months, and nine months
- One year
Auto-renewal
When the auto-renewal feature is enabled for an instance, the payment is automatically deducted based on the corresponding rules. Alibaba Cloud first attempts to deduct the payment by using coupons. If you have insufficient coupons in your account, Alibaba Cloud deducts the remaining payment by using your account balance.
Method for enabling auto-renewal | Available renewal duration |
---|---|
On the instance creation page | You cannot set the renewal duration. The auto-renewal duration is set by the system
based on the subscription duration of the instance.
Note You can modify the auto-renewal duration on the Instances or Renew page.
|
On the Instances page | You can set the renewal duration to one month or one year. |
On the Renew page | You can set the renewal duration to one month, two months, three months, six months, or one year. |
- The first auto-renewal day and billing cycle are calculated based on the expiration day of the instance.
- The auto-renewal duration is subject to the duration that you selected. For example, if you select three months, ECS renews the instance for three months each time before it expires until you disable auto-renewal.
- If you have manually renewed an instance before the auto-renewal payment is deducted, the auto-renewal operation will not be performed during the current billing cycle.
- If the auto-renewal deduction fails, the systemsends messages to your email address that is bound to your account. Check you email and handle the messages in a timely manner to ensure your business availability.
- Alibaba Cloud sends an email reminder on the seventh day before the instance expires (T-7).
- Alibaba Cloud deducts the payment for the next billing cycle from your bank card,
PayPal, or Paytm (India) account on the third day before the instance expires (T-3).
If the deduction fails, Alibaba Cloud continues to attempt to deduct the payment up
to four times on the following days until all the allowed deduction attempts fail
or the payment is deducted: the day before the instance expires (T-1), the day that
the instance expires (T), the seventh day after the instance expires (T+6), and the
fifteenth day after the instance expires (T+14).
- At 08:00:00 (UTC+8) on the deduction day, Alibaba Cloud performs auto-renewal in sequence on all ECS instances that are set to expire. This causes the actual renewal time to be between 08:00:00 (UTC+8) and 18:00:00 (UTC+8).
- If the payment is deducted before the fifteenth day after the instance expires (T+14), the next billing cycle of the instance starts on the day that the instance expires.
- If the instance fails to be renewed during the five preceding deduction attempts, the instance will enter the Stopped state on the sixteenth day after the instance expires (T+15). After the instance enters the Stopped state, you cannot log on to or connect to the instance. In this case, you must manually renew the instance. If the instance is not manually renewed within the 15 days after it enters the Stopped state, the instance is released and its data is lost permanently.
