> [Our service can only go down] five minutes and 15 seconds per year.

I don't have much experience in this area, so please correct me if I'm mistaken:

Don't these two quotes together imply that they have failed to deliver on their SLA for the subset of their customers that want their service in us-east-1? I understand the customers won't be mad at them in this case, since us-east-1 itself is down, but I feel like their title is incorrect. Some subset of their service is running on top of AWS. When AWS goes down, that subset of their service is down. When AWS was down, it seems like they were also down for some customers.

Had no idea that Route 53 had this sort of functionality
