[Outages-discussion] [outages] ipv6 packet loss in DEN for comcast?

[Hugo Slabbert]

(moving to -discussion)

That host appears to listen on TCP 25. Can you produce any viable results
with an mtr to TCP port 25 (mtr -T -P 25 mail.dragon.net) that show any
loss? Or any captures that indicate loss, retransmits, etc?
