AT&T Fiber in the SF Bay Area is flipping bits
If you have AT&amp;T fiber, run the script in the linked gist:<p><a href="https:&#x2F;&#x2F;twitter.com&#x2F;bmastenbrook&#x2F;status&#x2F;1335400747794530304" rel="nofollow">https:&#x2F;&#x2F;twitter.com&#x2F;bmastenbrook&#x2F;status&#x2F;1335400747794530304</a><p>It loads <a href="http:&#x2F;&#x2F;example.com" rel="nofollow">http:&#x2F;&#x2F;example.com</a> and <a href="https:&#x2F;&#x2F;example.com" rel="nofollow">https:&#x2F;&#x2F;example.com</a> and compares the result (should be equal) in a loop, and then reports if it finds a difference.  I&#x27;m seeing multiple bit flips in the unencrypted version, and having a lot of issues loading web pages, presumably because a corrupted packet in a TLS handshake is an error and the connection dies.<p>Tech support, even when Twitter accounts with a lot of followers message them, is completely useless, they just say that they don&#x27;t show any outages at your location.  They need to be flooded with complaints for someone to look at this, or maybe someone from AT&amp;T is on here that can get it looked at...
