T-Mobile Home Internet Can't Access Certain Sites/Cloud Services
Pasadena, CA - As of yesterday (11/9/2022) morning, I wasn't able to access certain websites/cloud (e.g. Ring.com, Alexa, a host of various work-related cloud-based services). Spent over an hour wit...
It's not just that the site/service is using AWS, it's that it's using IPv4 and AWS. The IPv4 routing is messed up. If I go to 'amazon.com' the DNS will resolve that to an IPv4 address, and that times out. If I go to 'www.amazon.com' the DNS resolves it to an IPv6 address and the connection succeeds. If I disable IPv6 on my PC's network adapter and go to 'www.amazon.com' it will connect, but it will be a lot slower and have pretty high packet loss.
I can confirm I wasted a lot of time troubleshooting this and was not able to use a lot of work and AWS services yesterday in Los Angeles.
