Bay Area AT&T Fiber Customers suffering bit flipping for two weeks
- stephen-mw 6y agoFor those wondering how bad the issue is, check out this[1] screenshot of a diff between the TLS/non-TLS html from www.example.com. Here's "corrupted" UTF-8 characters expressed as bits. In this example you can see clearly what's happening. The top byte is correct and the second one is corrupted. 01100111 # g 01101111 # o 01110000 # p 01111000 # x 01101100 # l 01100100 # d 01100101 # e 01101101 # m 1. https://i.imgur.com/qIMnTTe.png https://i.imgur.com/qIMnTTe.png

- mike_d 6y agoJesus this explains so many intermittent issues I've been having over the last week.
- zzarzzur 6y agoI'm on Fiber from Sonic and last week I was experiencing issues with connections randomly being dropped and being extremely slow to load. Sonic tech came out and said that the uplink was good and that it might be a problem with my UniFi system, but I don't have any issues with my LAN services. It's great that the community was able to diagnose this, but a shame that AT&T didn't pick it up first and isn't acknowledging an issue on their network.
