I am still seeing significant loss between my work (ESnet in Berkeley) 
and my home (Comcast Business Class in Uptown Oakland):

--- manasquan.burnttofu.net ping statistics ---

ESnet has a number of perfSONAR hosts (e.g. sunn-owamp.es.net) from/to 
which you can do ping and traceroute if that helps.

Similarly, I am seeing loss from UC San Francisco to my home network:

[tulare:~] ms% ping manasquan.burnttofu.net
PING manasquan.burnttofu.net (98.210.60.123): 56 data bytes

round-trip min/avg/max/stddev = 16.218/22.903/50.951/7.144 ms

I am not seeing any loss between UCSF and a VPS I have in Los Angeles.

Traceroutes from UCSF to home:
