This topic describes the changes in the service status of Message Queue for MQTT when you have overdue payments under your account or when your instance expires. To prevent the impact of overdue payments or instance expiration on your business, settle the unpaid bills or renew your instance at the earliest opportunity.

Overdue payments of pay-as-you-go instances

The billing cycle of pay-as-you-go instances of Message Queue for MQTT is 24 hours. On the next natural day, Alibaba Cloud charges your service use of the previous natural day, issues a bill, and deducts the service fees from your Alibaba Cloud account balance based on the bill amount. A bill is generally issued within 8 to 10 hours after the current billing cycle ends.

When your account balance is insufficient to pay the bill amount, the Message Queue for MQTT service is affected in the following aspects:
  • You can continue to use the Message Queue for MQTT service within 24 hours after the payment becomes overdue. After 24 hours elapse, Alibaba Cloud suspends the Message Queue for MQTT service, but temporarily retains the instance and resource data for you.
  • If you do not settle your unpaid bill within seven days after the service is suspended, Alibaba Cloud releases the instance that you create in Message Queue for MQTT and deletes the topics and group IDs that you create on the instance. The released instance and its resources cannot be restored.

Overdue payments of subscription instances

After your subscription instance expires, the service status changes in the following aspects:
  • You can continue to use the instance within 15 days after it expires. After 15 days elapse, Alibaba Cloud suspends the Message Queue for MQTT service for you, but temporarily retains the instance and resource data for you.
  • If you do not renew your instance within 15 days after the service is suspended, Alibaba Cloud releases the instance that you create in Message Queue for MQTT and deletes the topics and group IDs that you create on the instance. The released instance and its resources cannot be restored.
