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.”

A: fine A-: problems B+: servers are on fire

I really like Amazon as a company, use a lot of their services, but this is dishonest.

If netflix is down, then it's something most companies who know how to design fail over can't cope with.

Other services, like Twilio, have come through several of these major problems with US-EAST generally unscathed while Netflix has had issues repeatedly.
