Hello,
Cox IPv6 rolled out to my area in Cheshire, CT on February 16th. There was a bit of packet loss here or there for the next couple of days but no major disruptions. Last night (February 22) at about 8:30pm, IPv6 disappeared (according to pfSense), and I was receiving DHCP errors, which I've pasted below.
I tried resetting the modem and pfSense several times, with no luck. I figured it was an outage and left it alone until today, but the modem still won't give any DHCPv6 leases. I tried to eliminate pfSense as the cause by connecting the modem directly to my laptop and using dhclient -N and dhclient -P (for DHCPv6 and DHCPv6-PD, respectively). No dice.
IPv4 works properly on pfSense and the laptop.
Here is the relevant log output from pfSense:
$ clog /var/log/dhcpd.log | grep dhcp6

This is the output from my laptop with dhclient in DHCPv6 mode:

I'd appreciate any help with this issue, or confirmation that there is an outage in my area.
Thanks.
