If you wouldn’t mind a quick tracerooute - Can you confirm reachability to the following:
2001:500:84::b
Thanks in advance.

There should be a tool for this kind of thing!

or just the data (~1MB):

Measurement: 1666834 should be bill's measurement request... 50
icmptraceroutes from around the globez.

[shortened version for NANOG with only one attachment]
When you analyse these results with using my experimental tool LARA
http://labske.org/tools
you discover that local connectivity is through HE and Los Nettos.
Further you can see that about half the HE packets are sent via Los
Nettos, so the amount ofredundancy that local traffic distribution among
upstreams may suggest is not really there.
If you like we can run this again with more probes. Of course you can
also just get an account and run it yourself....
