I’ve resisted reaching out like this so far. I posted on DSL Reports and didn't get anything valuable back. I’m also confident that Spectrum front line support will have zero clue as to where to take my question. In a nutshell: seeing some strange IPv6 reachability issues, and they are always overnight/wee-hours (EST). Seems to be very specific to a certain prefix (or more pointedly - my IA_NA vs. IA_PD). If someone could contact me off-list I would greatly appreciate it. This isn’t a hard down or critical issue - but it is an annoying head-scratcher.
