Postponed: Ameritech NAP maintenance

  • From: Mark A. Cnota
  • Date: Wed Mar 10 15:53:12 1999

As luck would have it, within 90 minutes of my sending a notice out, I was
told the maintenance has been postponed. Timing is everything, they say.

Naturally, we will let everyone know as soon as a new date has been scheduled.

As before, customers with questions can contact me privately.

>>is going to perform an ATM switch migration from the Lucent GCNS 2000 to
>>an Ascend 550/500 platform.
>>      During this migration your circuit will go down and for how long

>>      In the event that you seem to be experiencing problems beyond the
>>scheduled maintenance window, call the AADS NMC (NOC) at 1-800-972-3441
>>with your Ameritech circuit ID and indicate that you are a NAP customer.
>>International customers can call 1-847-562-7690 for trouble reporting.
>>We appreciate your understanding and patience during this time.
