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).
