Yes. Totally agree. I am having to implement Atlassian Status Page right now and there is also no pre-built HubSpot integration with Status Page which is disappointing. While it would be nice for HubSpot to provide this, the reality is that most companies need to present a page that aggregates status information from several to many different sources (HubSpot, AWS, FreshDesk, etc) and potentially their own custom APIs and services. So, the large number of pre-bulit integrations is what makes Atlassian Status Page compelling and why they should really provide an integration for that.
This may not help you, but I noticed there is a new Performance API in beta that will provide prgrammatic access to performance data. If not, this is a least a sign that they are moving in this direction and that a basic HubSpot Status Page and pre-build integtrations for things like Atlassian Status Page may be coming.
