Most frequently used egress hosts
This diagram highlights that many of the egress URLs used in Forge apps are actually hosts owned by Atlassian. This is probably to support integrations with APIs that do not support OAuth or to embed images and avatars. It is likely that apps with only those URLs listed in their manifest.yml do not cause actual egress even though it is technically possible.
