I may be mistaken, but 2 hours only aligns with their post mortem for 80% of the impacted instances. By their own account there were instances impacted until 8AM and a small number after that even. Your monitoring sounds really comprehensive. That's a very cool way to advertise the service it's built on. Do you monitor service providers for outages that reduce capacity or increase latencies but otherwise the service is "up"?
