I have an off-topic question: This is the second company (after GitLab) I see with an “about” subdomain. Is this a new trend of using “about.x.com” for the marketing website and “x.com” for the web app? Is there a blog post or discussion about this?
On the technological side, I guess separate hostnames might make some ops things a little easier. But that alone can hardly be the reason. Easier and good looks can. Also: In a large scale outage, an about.x.com that is not running on your main cloud provider could be valuable for status updates, because far more people would know about about.x.com than about some status.x.com you might have if your "about" content was on the main hostname.
Is there a specific flag to enable ?
