I would agree with you, but Amazon is just downright dishonest in their reports, which makes me sad, because I love Amazon. Go look at the past reports, they've never shown a red market, only "degraded performance" even when services for multiple availability zones went down at the same time due to their power outage (so had you architected to multiple AZs you were still fucked). When they have a single AZ go down, they won't even give it a yellow marker on the status page, they'll just put a footnote on a green marker. It makes their status dashboard pretty much useless for at a glance checking (why even have colors if they don't mean anything?)

Read their report from the major outage earlier this year, they start out by saying "elevated error rates", when many services were in fact down, and it wasn't until hours later they finally admitted to having an issue that affected more than just one availability zone.

From Forbes: ”We are investigating elevated errors rates for APIs in the US-EAST-1 (Northern Virginia) region, as well as connectivity issues to instances in a single availability zone.” By 11:49 EST, it reported that, ”Power has been restored to the impacted Availability Zone and we are working to bring impacted instances and volumes back online.” But by 12:20 EST the outage continued, “We are continuing to work to bring the instances and volumes back online. In addition, EC2 and EBS APIs are currently experiencing elevated error rates.” At 12:54 AM EST, AWS reported that “EC2 and EBS APIs are once again operating normally. We are continuing to recover impacted instances and volumes.”
