According to the AWS status page, only one availability zone within US-East is down, not the whole US-East region. Running a highly-available service exclusively from US-East is a reasonable strategy as long as you're spread across multiple availability zones. I'm not an AWS customer, just reading their docs; please correct me if I'm wrong about any of this.
