Wait until you get smurfed and ask them to use the MCI-developed tracing
tools and get a "duhhhhh" back in response.
They might have fixed this by now (since we bitched LOUDLY about this) but
as of a few weeks ago the NOC had *no idea* how to trace this kind of
activity - at all - nor any desire to learn.
Yes, we have them, and will attempt to use them in a real time
situation if it occurs.
