Fairpoint backhaul - three providers now?
I'm not expecting anyone from Fairpoint to actually post here, but...
I have been trying to figure out if Fairpoint replaced the backhaul to Verizon (alter.net).. I am now thinking they have not replaced it, but brought online additional backhaul providers (cogentco.com and above.net).
I believe they are doing some sort of load balancing across their providers.
Here's how I found it:
1. Do a traceroute to 126.96.36.199.
# traceroute 188.8.131.52
traceroute to 184.108.40.206 (220.127.116.11), 30 hops max, 60 byte packets
1 * * *
2 18.104.22.168 (22.214.171.124) 4.783 ms 4.792 ms 4.779 ms
3 POS3-0-0.GW3.BOS4.ALTER.NET (126.96.36.199) 6.908 ms 6.917 ms 6.905 ms
4 0.so-0-1-1.XL3.BOS4.ALTER.NET (188.8.131.52) 6.904 ms 6.904 ms 6.899 ms
2. Do a traceroute to 184.108.40.206.
# traceroute 220.127.116.11
traceroute to 18.104.22.168 (22.214.171.124), 30 hops max, 60 byte packets

When I did the above test, the IP ending with 103 was sent through cogentco.com and the IP ending with 104 was sent through alter.net. If you get the same provider for both traceroutes, change the IP ending from 103 to 101 and try again. Keep changing it down by one number until you see the other provider route your traffic.
Both of the above IPs belong to the "www.google.com" server pool.
The "above.net" provider was used to connect me to www.yahoo.com.
# traceroute www.yahoo.com
traceroute to www.yahoo.com (22.214.171.124), 30 hops max, 60 byte packets

Having multiple peering agreements and allowing us to have access to the three providers is a good improvement to the bandwidth starvation we have been subjected to.
Now the real question.. Is this going to be the long-term fix for Fairpoint or just until the peering agreement with Verizon (alter.net) expires?

Funny you should mention this, I just discovered something similar -
I'm seeing most US traffic going out over Above.net but if I check something in the UK, it still goes out over alternet. I would guess that they are routing their traffic based on peering costs.
At the same time, something is still not right with their routing as of last night and through this morning. I'm seeing oddities that I can't quite figure out yet.
