Three things that BC should keep in mind about unauthenticated or guest user access are A, B, and D.
Unauthenticated or guest useraccess is a feature that allows users to access your Experience Cloud site without logging in or registering. Unauthenticated or guest users have limited access and visibility to data in your Salesforce org, and they have some restrictions, such as:
* Guestuser external organization-wide defaults are always set to Private. This means that guest users cannot access any records that are owned by external users (such as Customer Community or Partner Community users) unless they are explicitly shared with them.
* Guest user can't access records via manual sharing. This means that guest users cannot access any records that are shared with them by using the Sharing button on the record detail page.
* Guest user can't be members of public groups or queues. This means that guest users cannot access any records that are shared with them by using public groups or queues as criteria.

To prevent usability issues, CK should provision and activate CDN in those regions where traffic is high. A CDN is a network of servers that delivers cached static content from websites to users based on the geographic location of the user. By provisioning and activating CDN in high-traffic regions, CK can improve the performance and availability of their public site for their users.
