So if one hosts one's site on AWS, then your system probably isn't going to work, eh? :)
If AWS goes down, your site and mine both go down together. This was basically why Pagerduty got out to an early win -- they never used AWS when everyone else did.
Where you host is underrated. When I started building on-call for Rootly the first thing we did was build a multi-cloud setup (AWS and GCP) for honestly pretty overkill reliability. Don’t regret it one bit.
