AT&T Fiber in the SF Bay Area is flipping bits

Thanks for sharing this! I have long suspected that TLS does this. It is great: for many applications preventing bitflips in transit is arguably more important than privacy. Is there an authorative source where this is documented?

You mean besides the RFCs (the most recent RFC 8446 describes TLS 1.3) ?

https://tools.ietf.org/html/rfc8446

If you aren't interested in why this works just the Introduction to the RFC explains the intent, specifically what we care about here is that TLS delivers:

"Integrity: Data sent over the channel after establishment cannot be modified by attackers without detection."

And further notes "These properties should be true even in the face of an attacker who has complete control of the network".
