Limitations

The following are a few limitations to consider while using CDN:

  • Limited Points of Presence (PoPs): CDN currently offers network edge servers focused on the European region and will soon extend the PoPs to other locations.

  • Restricted Customizations: You can only turn the Caching and WAF settings on or off. The option to customize these in the routing rule is not available.

  • Distributions: A maximum of twenty distributions can be created per contract. If the quota needs to be increased, contact IONOS Cloud Support.

  • Routing Rules: A maximum of 25 routing rules can be added for a distribution.

  • Certificate Authority Support: CDN trusts and accepts SSL/TLS certificates issued by recognized and reputable Certificate Authorities (CAs) to ensure high security and reliability. Examples of commonly supported CAs include, but are not limited to:

    • GeoTrust

    • Let's Encrypt intermediate certificates:

      • R5

      • R6

      • R10

      • R11

      • R12

      • R13

      • R14

    • GlobalSign

Note: Self-signed certificates are not accepted, as security policies require certificates to be issued by established and trusted authorities.
