We have feedback from the community that 3D Warehouse is inaccessible. We have found this to be the case especially in the UK.
There are DNS problems for end users on British Telecom ISP in the UK
Updates from http://status.aws.amazon.com/:
5:33 AM PDT We are investigating connectivity problems between CloudFront and end users on certain ISPs in the UK.
6:17 AM PDT We can confirm that end users using a single ISP in the UK are experiencing connectivity problems when trying to reach CloudFront. We are working to resolve this issue.
7:04 AM PDT End users using a single ISP, British Telecom, in the UK are experiencing failures when resolving cloudfront.net domain names. We are working with the ISP to resolve this issue. As a workaround, end users can change their resolvers to use a public DNS resolver and successfully resolve cloudfront.net names.
