[FIXED] Internap Denver <-> HE Connectivity is down

This morning I noticed all my IPv6 Tunnels going thru Internap were down, regardless of tunnel endpoint.
all other tunnels were working fine on other providers.

I cant ping any tunnelbroker IPv4 endpoint, 97.5% packet loss over several hours.

I figured the issue was with my upstream provider who uses internap for there primary carrier, they quickly submitted a ticket on my behalf and this was the reply from there support team.

It looks like Hurricane-Electric is having issues. I dont have any
problems getting to the IP from outside Denver, where routes go over
Savvis, but as soon as I try going from a box in Denver, where once
packets leave our PNAP and hit Globix, there are issues. Since the IP in
question belongs to Hurricane-Electric we are going to have to say that
this issue belongs to them.

Can you comment if your having peering issues currently in Denver, CO?



All of our Internap ipv4/ipv6 peering is up, and without any sessions having bounced. Also we don't have presence in Denver, so no we wouldn't be having any issues there. Maybe some traceroutes, or telling us your IPv4 endpoint so we can test the return path, or you can do this with our looking glass.

nayrnet is my endpoint, and its trying to connect to

which is fmnt2, I try to ping back thru looking lass and it fails as well.


my other tunnel is going through from and has the same issue, cant ping either end..

I gave the support ppl your looking glass addy and they quickly took ownership off the issue and have resolved it, all my tunnels are working great once again. Thanks for the assistance.
