[tor-relays] Connectivity issues; disabling my relay

[grarpamp]

Apparently some change to hw/fw/sw/topology was made.
If the isp's say nothing changed then you'd want to test
and graph every layer2/3 / tunnel hop on the way out to
the internet, including to the node of some neighbor on
the same fiber or headend as you, as well as the same
set of tests from an unaffected neighbor.
That's a large % drop in latency, though neither that or
pkt loss necessarily means anything nefarious.
