This appears to be a single region outage - us-east-1. AWS supports as much redundancy as you want. You can be redundant between multiple Availability Zones in a single Region or you can be redundant among 1, 2 or even 25 regions throughout the world. Multiple-region redundancy costs more both in initial planning/setup as well as monthly fees so a lot of AWS customers choose to just not do it.
