    How can I view regions and availability zones?

    To view regions and availability zones, use the following methods:

    What are available CVM regions and availability zones and how to choose?

    For more information on available CVM regions and availability zones, see Regions and Availability Zones.
    For more information on how to choose regions and availability zones, see How to Select the Region and Availability Zone.

    Can I change the region of a purchased CVM?

    No. You cannot change the regions of purchased CVMs. To change regions or availability zones, use the following methods:

    • Terminate instances and then purchase a new one.

    • Create a custom image for the original instance. Then, use the custom image to create an instance, launch it and update its configuration in a new availability zone.

      1. Create a custom image for the current instance. For more information, see Create Custom Images.
      2. If the network environment of the current instance is VPC and the private IP address must be retained after migration, you need to delete the subnet in the current availability zone and then create a subnet in the new availability zone with the same IP address range as that of the original subnet.

        If the subnet to be deleted contains available instances, first migrate all instances in the subnet to the new subnet.

      3. Use the newly created custom image to create a new instance in the new availability zone.
        You can choose the same instance type and configuration as that of the original instance, or configure new ones for the new instance. For more information, see Creating an Instance.
      4. If an elastic public IP address is associated with the original instance, disassociate it from the original instance and associate it with the new instance. For more information, see Elastic IP Addresses (EIPs).
      5. (Optional) If the pricing modes of the original instance is pay-as-you-go, you can terminate it. For more information, see Terminate Instances.

    Can Tencent Cloud users in China enjoy the same product quality and services for resources purchased in China and other regions or countries?

    Yes. Tencent Cloud China Console provides all users with the same product quality and services. The purchase region will not affect your user rights on the console.

    Can I use the replication feature of a custom image to migrate a CVM in China to another country or region?

    • No. Images can only be replicated within the same country or region. To replicate images between countries, please submit a ticket to apply.

    What are the differences between instances in and outside the mainland of China, and how do I determine which region fits me the best?

    Instances in other countries or regions are deployed outside the mainland of China, providing geographical and market advantages for global users. The fast local network can also meet international customer needs, which is suitable for users who run businesses in other countries or regions.

    Can I change between Linux and Windows operating systems for a CVM instance purchased in a region outside the mainland of China?

    CVM instances in all regions support reinstalling an operating system of the same type (Linux is reinstalled as Linux, Windows is reinstalled as Windows).
    Only CVM instances in the mainland of China support reinstalling an operating system of a different type (Linux is reinstalled as Windows, Windows is reinstalled as Linux).

    How do I apply for after-sale services for products purchased in regions outside the mainland of China?

    If you purchased a product on the Tencent Cloud official website, call the Tencent Cloud 24/7 service hotline (95716) or submit a ticket.

    How do I deploy CVM instances in regions outside China?

    CVM instances in regions in and outside China have the same deployment method if they have the same type of operating system.

    Can I migrate instances to regions outside the mainland of China?

    The region and availability zone of an instance cannot be changed. To use an instance in other countries or regions, you need to purchase another instance.

    Why some instance types can only be purchased in China regions?

    Some regions may not support certain instance types. For information on supported instance types, go to the CVM purchase page to view instance purchase information.

    If I build a website using a CVM instance from a region outside the mainland of China and my users access the website through a domain name, does this domain name need ICP filing?

    For websites in regions in the mainland of China, ICP filing is required for domain names. For websites in other countries or regions, ICP filing is not required. For more information, see ICP Filing Overview.

    Do instances in different regions have the same price?

    The pricing of a CVM instance includes its specifications, storage, network bandwidth, etc. The prices of these components vary by regions, so the instance price will be different.
    For more information on pricing, see Pricing.
