The status page is hosted on AWS Cloudfront, right? It sure looks like Cloudfront was overwhelmed by the traffic spike, which is a bit concerning. Hope we'll see a post from their side.
It looks a lot like a CloudFront error we randomly saw today from one of our engineers in South America. I suspect there was a small outage in AWS but can't prove it.
This situation reminds me of risk assessment, where you sometimes assume two rare events are independent, but later learn they are actually highly correlated.
