You can change the Internet bandwidth of your pay-as-you-go instance if it does not meet or exceeds your business requirements.

Background information

You can change the Internet bandwidth of a pay-as-you-go instance based on the network type and the public IP category of the instance, as listed in the following table.
Network type Public IP category Available feature
VPC Elastic IP address (EIP) Change the bandwidth of the EIP
Allocated public IP address Change the bandwidth of the pay-as-you-go instance
Classic network Allocated public IP address Change the bandwidth of the pay-as-you-go instance
After you change the bandwidth of a pay-as-you-go instance, you cannot change it again in the next 5 minutes. When you change the bandwidth of a pay-as-you-go instance, you can perform the following operations:

  • Set a new Internet bandwidth value. After the Internet bandwidth is set to 0 Mbit/s,
    • For a VPC-type instance, its public IP address is released immediately.
    • The public IP addresses of classic network-type instances are retained, but do not provide public access.
