For customer who have restrictive network, it is important that the IP ranges information as specified on Atlassian Cloud IP ranges and domains page are up to date and fully configured on their side to avoid service disruption. At the moment, there is no way to keep updated if the IP address range and domains are changed. 

It would be really helpful if there would be a way to notify the administrators for any changes on the Atlassian Cloud IP ranges and domains page.

Option 1: Add a watch option on Atlassian Cloud IP ranges and domains page 

Option 2: Notify the Technical contacts when the Atlassian Cloud IP ranges and domains page gets updated.
