MCI/MAE-East/PSI losses unacceptable

  • From: William Allen Simpson
  • Date: Mon Mar 18 19:35:50 1996

What is going on out at MAE-East?  From Michigan, I'm seeing a
tremendous loss there, all day (since 10 am) between
mae-east-plusplus.Washington.mci.net. and mae-east.psi.net.  It is
completely impossible to POP3 my email.  SUNOS just times out the TCP
connection after about 10KB in 1/2 hour.

Pinging every 2 seconds for over 20 minutes:

Of course, there is a 20% loss on MCI net alone.  Seems to be after West
Orange.

Whatever happened to the Chicago NAP?

What can we do to fix this problem?
