Limitations

Certain limitations and quotas are in place to protect the infrastructure, and ensure a high level of security and performance:

  • Downgrades are not possible. Cloud servers can only be upgraded to a more powerful plan, with the option to revert the upgrade within 72 hours.

  • Images are region-specific. An image uploaded to one region can be used only for instances within that region.

  • Modifying individual resources is not supported. Memory, vCPU, or disk configurations cannot be modified independently. For additional storage, you can attach a virtual drive to the cloud server.

  • Only one public IPv4 address is provided. Each cloud server is limited to a single public IPv4 address. Alias addresses are not supported, but an IPv6 address can be ordered separately.

  • Operating system reinstallation can be done only to the same type. Reinstallation can be performed only from Linux to Linux or from Windows to Windows.

  • Linux and Windows servers can only be hosted separately. Cloud servers running on Linux and Windows are always deployed on separate physical nodes.

  • User data can be accessed only via the Public API. Managing and injecting user-specific data into cloud instances can be done only through the Public API.

By default, the following quotas are applied per account:
