Connectivity issue tonight?

Is anyone else seeing a connectivity issue tonight? I haven't been able to reach my server for a couple of hours. It went down while I was ssh'd in… However, my friend's linode is reachable (it's on ThePlanet). My traceroute falls off just as it transitions out of alter.net:

6 POS6-0.GW4.IAD8.ALTER.NET (152.63.41.29) 31.470 ms 31.080 ms 31.077 ms

7 wcgGigE-gw2.customer.alter.net (157.130.30.246) 36.555 ms 31.119 ms 31.356 ms

I believe hop 8 was the first hop into Hurricane Electric from where I am. If you're on one of the HE nodes (host9 and up), try a traceroute to 206.114.241.1 (one of my upstream hops) and see if you get through.

I am also timing out on the first hop after HE.net:

Can you guys log in via the console? Or trace to the host, but not the Linode?

If you can get in via console, what's the output of "arp -n"? Specifically the address of the gateways.

www root # arp -n

Address HWtype HWaddress Flags Mask Iface

66.220.1.1 ether 00:30:71:F0:1C:55 C eth0

My friend set up an account for me on his linode, and from there I can get into mine (I can't console to mine directly). Here's the arp output:

Address HWtype HWaddress Flags Mask Iface

65.19.178.1 ether 00:30:71:F0:1C:55 C eth0

Those are both correct… /me hmms

Interesting… tracerouting back to home from my linode makes it look like the failure I'm seeing is actually in alter.net:

@NecroBones:

I was seeing the same thing from here, but inside (or after) wcg.net. I was able to access through XO and ThePlanet, however. Whatever it was, it seems to have corrected itself. Let me know if there are any more problems.
