I suspect that you are going out via the CIX-SMDS cloud, not MAE-East -
PSI is not on MAE-West.

I also suspect that if/when you have packet loss it is due to the
shared FDDI at MAE-East.  PSI (along with several other service
providers) is on the shared FDDI at MAE-East.  The MAE-East shared FDDI
is quite overloaded (it hits 90 Meg during the day).  [The MAE-East
Gigaswitch is humming along quite nicely at a total of just over 190
Meg during the day.]

The shared FDDI participants at MAE-East are:
Shared FDDI     192.41.177.6    wtn9-mae_east-ce.sura.net
Shared FDDI     192.41.177.7    (unknown) (down)
Shared FDDI     192.41.177.75   mae-east.iconnet.net
Shared FDDI     192.41.177.95   mae-east.delphi.com
Shared FDDI     192.41.177.110  mae-east.ibm.com
Shared FDDI     192.41.177.140  mae-east.ans.net
Shared FDDI     192.41.177.163  (unknown)
Shared FDDI     192.41.177.243  gsl-mae-e-fddi1/0.gsl.net
Shared FDDI     192.41.177.245  mae-east.psi.net

Check out the MFS MAE-East/West web pages at http://www.mfsdatanet/MAE/
for this and other data.  There are daily graphs of traffic and a list
of the connections to each MAE (showing how each provider is
connected).
