I'm seeing 60% packet loss at tserv15.lax1.  That's... fairly unpleasant.
Does anyone else see this kind of problem?

The PL didn't continue next hop, its 0% until the destination. Might have loss on the return path or an issue itself at the destination.

Thanks for the quick reply.  Btw, some of the IPs and names in the original post were anonymized.

I ran mtr from outside in, and it sees losses of 1 to 8% ofver all the hops.  I see 60^ loss on the tserv15.lax1 hop,a dn also 60% at hops near the destination.  Here is tracing to google:

6. ???
7. me        4.7%   465   55.8  36.7  12.4 181.9  42.4

I'm not really sure how to use mtr to tell which side has the loss, unfortunately.
