I've always been a proponent of separating the monitoring from the infra. Otherwise your insight is binary: the service is either up or down. You don't have an context as to why.
Edit: Additionally, from a competitive standpoint, I don't see a problem with using a third-party platform for a monitoring service.
Yes, this is always one of our primary questions we ask when deciding when and how we should dogfood our own services; will we create a circular dependency where our ability to fix an issue on one service is hindered by any chain of dependencies between the service with the issue and the service used to fix it. We always avoid those, or at least have easy alternatives.
Absolutely agree about an external monitoring service being a necessity. I was more referring to cloudflare.com (and specifically dash.cloudflare.com) being entirely served through Cloudflare itself, or the AWS console being hosted on AWS, etc.
