Brad and I have also started seeing icmp problems to LSU today.  lots of
dropped packets, etc...  weird thing is it only happens from SLU, works
fine from home on i-55 (perhaps an internet2 issue...).  Also only seems
to affect their 130.39.184.0/24 subnet...  the few other subnets i picked
worked fine.  I have not noticed any other problems, only icmp.  Weird...

Also had some interesting results using ping -R (record route)

a quick search turned up this tcp ping... looks like it just sends a SYN 
to port 1884 and measures round trip.  unfortunately it doesn't say 
anything about dropped packets. YMMV... let me know if you find something 
better.
