Summary

Currently, customers who restrict internet access and allowlist only the official IP addresses and domains for Atlassian Cloud products will experience rendering issues with Smart Links. This is because Smart Links rely on external Content Delivery Networks (CDNs) that are not included in the official documentation.

Description

A customer who has a network environment with internet access disabled by default, and only allows access to domains specified in the official guide, has reported that Smart Links display incorrectly.

The customer's investigation using developer tools confirmed that resources from https://npmcdn.com are not being loaded. This domain is not listed in the official guide. The customer's setup is correctly implemented according to our documentation, but the feature does not function as expected due to this undocumented dependency.

Suggested features

The official IP address and domain guide should be updated to include all necessary external CDN domains required for Atlassian Cloud features, such as Smart Links, to function properly. Alternatively, the Smart Link feature should be modified to retrieve all necessary assets from domains that are already included in the official allowlist to avoid external CDN dependencies.

Expected outcome

Customers in secure, restricted network environments will be able to use the Smart Link feature without experiencing visual or rendering bugs. This ensures that the Confluence user experience is consistent across all network environments and that our official documentation is complete and accurate.
