Upgrading Instance Specifications

If your services evolve and you require higher instance specifications after purchasing an instance, you can upgrade these specifications.

Fees Description

Modifying specifications will lead to fee changes. For details, see Pricing of a Changed Specification.

Limitations and Constraints

  • If a customer purchases a non-BGP triple-line instance (not for sale currently), the specifications cannot be upgraded. To change the elastic bandwidth, submit a service ticket for technical support.
  • The lines cannot be changed during the upgrade.
  • Expired instances do not support specifications upgrades.
  • Frozen instances do not support specifications upgrades.

    Parameter

    Description

    Basic Protection Bandwidth

    The basic protection bandwidth is purchased by customers. If the peak attack traffic is less than or equal to the basic protection bandwidth, customers do not need to pay extra fees.

    Elastic Protection Bandwidth

    Elastic protection bandwidth is the maximum available defense bandwidth. The elastic protection bandwidth is not a part that is added on top of the basic protection bandwidth. If the elastic protection bandwidth is the same as the basic protection bandwidth, the elastic bandwidth will not work.

    Service Bandwidth

    The service bandwidth indicates clean service bandwidth forwarded to the origin server from the AAD scrubbing center. Each instance includes 100 Mbit/s of service bandwidth at no charge. If the AAD equipment room is outside of Huawei Cloud, it is recommended that the purchased AAD service bandwidth be equal to or greater than the egress bandwidth of the origin server.

    Protected Domain Names

    This parameter is available only for domain-based instances.

    Forwarding Rules

    This parameter is available only for IP-based instances.

  6. After you click Submit, the system will determine whether the configuration has changed. If the configuration does not change, the system displays a failure message indicating that selected specifications are the same as original specifications. If the configuration has changed, the Details page is displayed.
  7. Click Submit Order. When the payment is successful, the Order submitted successfully page is displayed.
