UPDATE 2021.04.07: Comcast has been stable for the better part of 24 hours so I'll declare things up and running again. Now the trouble is that I have a new public i.p. address, so I have to update that address in the other end of my point-to-point VPN links, which is not going well.
Comcrap has been up and down all morning (mostly down) so the Broward area feeds have followed suit.
I'm not declaring that things are back up until at least tomorrow. Comcast's app first said it would be repaired by 3PM, then when I checked an hour later it said by 4PM. Extending the promised repair time is their oldest trick in the book.
Just be patient. You be patient, sir, or you won't get anything.
