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.
