Hi guys (and sorry for the noise),
It appears return traffic from Charter to our ASN is blackholed.
According to all three of our upstreams they are delivering traffic but
it's not coming back. Unfortunately I don't have a reverse traceroute
(our emails to charter customers are bouncing) so I have no idea what
transit path they are returning traffic on. I tried fiddling with our
outbound paths to no avail. If someone on a Charter connection could
shoot me a traceroute to 209.9.238.7 that would be great. Ultimately if
someone from Charter is willing to help that would be awesome as well.
