This topic describes the impacts of overdue payments on Elastic Compute Service (ECS) resources and methods for handling overdue payments.
Causes
If the credits in your Alibaba Cloud account, including the account balance and vouchers, are insufficient to cover the required payments, your account has overdue payments.
Impacts of overdue payments
Subscription resources
You paid upfront for subscription resources and can use the resources as expected even if payments become overdue in your account. When your account has overdue payments, you cannot perform operations that generate fees, such as purchasing new instances, upgrading instance configurations, or renewing subscription resources.
If your subscription instance uses the pay-by-traffic billing method for network usage, the instance can no longer use the public bandwidth service after payments become overdue.
Pay-as-you-go ECS resources
The system attempts to deduct the fees for pay-as-you-go resources three times: on the due date (T), day T+7, and day T+14.
Within 15 days after a payment becomes overdue
If the fees for a pay-as-you-go instance fail to be deducted on day T, the payment for the instance becomes overdue. Within 15 days after the payment becomes overdue, the instance continues running. You can continue using existing resources, but cannot purchase resources, renew resources, or upgrade instance configurations. The system attempts to deduct the fees on day T+7 and day T+14.
More than 15 days after a payment becomes overdue
If all attempts to deduct the fees for the pay-as-you-go instance fail, the instance is stopped on the 15th day after the due date (day T+15) and billing for the instance also stops. More than 15 days after the instance is stopped, the system releases, detaches, or disassociates the resources of the instance.
The following table describes whether resources of an ECS pay-as-you-go instance are retained or released within and more than 15 days after the instance is stopped.
Resource
Within 15 days after the instance is stopped
More than 15 days after the instance is stopped
Computing resources (vCPUs and memory)
The computing resources (vCPUs and memory) of the instance are retained, but the instance stops providing services.
After an instance is stopped, you cannot connect to the instance or access the websites that are deployed on the instance. Service errors may also occur.
The computing resources (vCPUs and memory) are released.
NoteIf your computing resources (vCPUs and memory) are released due to overdue payments, the system sends you an email notification.
Block storage devices
Cloud disks and data that is stored on the cloud disks are retained, but the cloud disks become unavailable.
Local disks and data that is stored on the local disks are retained, but the local disks become unavailable.
NoteAfter cloud disks or local disks become unavailable, they cannot properly process read/write requests. This affects the operation of the instances to which the disks are attached. For example, the read/write performance of applications may significantly degrade, an extended period of time may be required to perform specific operations, or instances may be unexpectedly shut down or cannot restart if the instances use specific operating systems.
Cloud disks are released and data that is stored on the cloud disks cannot be recovered.
NoteData disks that are created together with pay-as-you-go instances and pay-as-you-go data disks that are separately created on the Disks page in the ECS console are released.
Local disks are released and data that is stored on the local disks cannot be recovered.
IP addresses
If the instance is located in the classic network, the public IP address of the instance is retained.
If the instance is located in a virtual private cloud (VPC), the following rules apply:
The public IP address is retained.
ImportantIf the economical mode is enabled before the instance is stopped, the public IP address of the instance may be recycled after the instance is stopped due to an overdue payment. The public IP address may change when the instance is started again.
The elastic IP address (EIP) that is associated with the instance remains unchanged.
If the instance is located in the classic network, the public IP address of the instance is released.
If the instance is located in a VPC, the following rules apply:
The public IP address is released.
The EIP is disassociated from the instance.
Snapshots
All snapshots are retained, but automatic snapshots cannot be created.
All snapshots are deleted, except for snapshots that were used to create cloud disks or custom images.
Service suspension prevention and handling
Settle overdue payments
If your account has overdue payments, your instances may be stopped. Settle overdue payments at your earliest convenience to prevent service suspension.
Release resources that are no longer needed
Back up and then delete resources that you no longer need in a timely manner.
Specify an alert threshold
Log on to the Billing Management console and specify an alert threshold on the Account Overview page. This way, if your account balance is lower than the alert threshold, you are automatically notified with a text message.
Specify the automatic release time
Specify an automatic release time for pay-as-you-go instances to prevent unnecessary costs and overdue payments. For more information, see Release an instance.
