Expiration and Overdue Payment

The following describes arrears and expiration of ModelArts dedicated resource pools:

Resources billed on a pay-per-use basis will not expire. Such resources are billed by the hour. If the balance is insufficient, your account will be in arrears. Then, resources will be frozen. Top up your account to unfreeze the resources. After your account is in arrears, the resources enter the grace period and then retention period.
After a yearly/monthly resource expires, it enters the grace period and then retention period.

You can access and use the resource pool during the grace period. If you do not renew the resource pool within the grace period, the resource enters the retention period and the resource status changes to Frozen. You cannot perform any operation on the resource in the retention period. If the resource pool is not renewed after the retention period ends, the resource pool will be automatically deleted.

If resources are renewed within a retention period, pay for the period from the time the resources enter the retention period to the time the resources are renewed.

Outstanding Balance

If your account is in arrears, some operations will be restricted. Top up your account as soon as possible. Table 1 describes the restricted operations.
