Overdue payments
When your account has an overdue payment, Edge Node Service (ENS) suspends your services. If the overdue payment remains unsettled after the retention period expires, ENS releases your resources. Settle the overdue payment to restore your service.
Impact of overdue payments
An overdue payment occurs when the available balance of your account, including your Alibaba Cloud account balance and vouchers, is less than the amount of an outstanding bill. An overdue payment can interrupt your ENS services. Top up your account in time.
Overdue payment notifications
After your account enters the overdue state, the system immediately sends you a reminder by SMS or email to settle the bill as soon as possible.
Service suspension
If your account has an overdue payment, limitations apply to your ENS resources based on the billing method.
Pay-as-you-go ENS resources
When your account has an overdue payment, your pay-as-you-go ENS resources are stopped or suspended.
After your account has an overdue payment, ENS automatically suspends the service. If the overdue payment persists for 15 days, ENS detaches and releases all your pay-as-you-go resources.
If you do not settle the overdue bill and start your instances again before your resources are released, your resource configurations are deleted and cannot be recovered.
Subscription ENS resources
After your account has an overdue payment, you can continue to use your existing subscription ENS resources, but the following limitations apply:
You cannot perform operations that incur fees, such as purchasing new resources, upgrading or renewing instances, or expanding cloud disks.
If a subscription ENS instance has pay-as-you-go cloud disks attached or uses pay-as-you-go Internet bandwidth, the cloud disk and Internet bandwidth services become unavailable after the overdue payment.
Resource retention rules
The following table describes the retention status of ENS resources during the overdue period.
| Resource type | Within 15 days after the overdue payment | After 15 days of the overdue payment |
| Compute resources (vCPUs and memory) | ENS retains your compute resources (vCPUs and memory), but you cannot start the instances. | ENS releases your compute resources (vCPUs and memory). Your business data is permanently deleted and cannot be recovered. |

| Public IP addresses | ENS retains static public IP addresses. Associated elastic IP addresses (EIPs) are not affected. | ENS releases static public IP addresses and detaches the associated EIPs. |
| Snapshots | ENS retains all snapshots and custom images, but you cannot use existing snapshots to create new cloud disks or custom images. You cannot manually create snapshots, automatic snapshots are no longer created, and operations that create custom images from instances fail because snapshots cannot be created. If you top up your account to settle the overdue payment, you can use your existing snapshots again, and your automatic snapshot policies are automatically re-enabled. | ENS cleans up and deletes all your snapshot resources. The data cannot be recovered after cleanup. |
Although you cannot use your existing snapshots during the overdue period, the storage of your existing snapshots continues to incur charges. As a result, your overdue amount keeps increasing.
Snapshot data continues to incur charges until it is cleaned up. If you no longer need the snapshot service, make sure to delete your snapshot data.
