Operational issue: Packet loss at Pacbell NAP

Several of my peers at PB NAP are reporting significant loss (>10%) over the
PB NAP. All are OC3 connected, and it seems that PB doesn't have the
ability to look too closely at OC3 connections.

Death of the 'net predicted: film at 11.

So, does this mean that ATM NAPs also have problems with high traffic load?
