I've got coworkers who are on campus, and can access AWS (and AWS-based sites) fine. Their connection to AWS is via the CENIC ISP, which peers directly to AWS.
Me, at home, on Comcast, I cannot connect to AWS-based sites, nor to the AWS console.
[RESOLVED] External Connectivity Issues
Between 11:43 AM and 1:30 PM PST some customers may have experienced connectivity issues between an external provider outside of our network and AWS destinations. This issue impacted connectivity originating from California. Connectivity to instances and services within the Region was not impacted during this issue. All AWS Services have been, and continue to operate normally.
