Common questions about Global Accelerator (GA) bandwidth plans. If your question isn't covered here, open a ticket with Alibaba Cloud Support.
What types of bandwidth plans does GA provide?
GA provides basic bandwidth plans.
A basic bandwidth plan provides bandwidth for data transfer over the Internet and within Alibaba Cloud. To use the GA service, you must purchase a basic bandwidth plan. Basic bandwidth plans are available in the following bandwidth types: basic, enhanced, and premium. The acceleration type, accelerated backend service, and acceleration scope of a basic bandwidth plan vary based on the bandwidth type. For more information, see Purchase and manage basic bandwidth plans.

Do basic bandwidth and enhanced bandwidth differ in quality?
No. Basic bandwidth and enhanced bandwidth apply to different scenarios but deliver the same bandwidth quality. For a full comparison, see Purchase and manage basic bandwidth plans.
What scenarios does premium bandwidth apply to?
Premium bandwidth is ideal for scenarios where both the acceleration region and the service region are outside the Chinese mainland. It accelerates Internet-facing services regardless of whether they run on or off Alibaba Cloud.
To accelerate traffic between the Chinese mainland and regions outside the Chinese mainland, select China (Hong Kong) as the acceleration region.
Can I downgrade a bandwidth plan?
Not currently. Basic bandwidth plans support upgrades only and cannot be downgraded.
What do I do when I get an error disassociating a bandwidth plan from a GA instance?
Delete the listeners and acceleration areas of the GA instance before disassociating the bandwidth plan:
Delete each listener configured on the GA instance.
Delete each acceleration area configured on the GA instance.
Disassociate the bandwidth plan from the GA instance.
