WorldComm Fiber Cut????

HHHMMM... Very interesting.  Someone who believes what a carrier really 
tells them.

If you go to the MFN homepage & click on the graphs listed below, then you 
might see that possibly the data being displayed is both inaccurate, as well 
as misleading.

Go to SJC OC3 Los Angeles, to OC192 SJC3 to SJC4, to OC12 MaeW ATM, OC48 # 2 
for IAD to NYR, IAD # 2 to PAIX VA OC48, DCA2 to DFW2 OC48, PAIX OC12 to 
Core1.sjc, NPA - DS3 to San Jose, LGA1 OC192#2 to IAD, LGA1 OC48 to Chicago, 
NYC Backbone OC192 to LGA2, NYC Backbone OC48 # 2 to core3.lga1, ETC...

Each one of these graphs shows abnormalities in the flow of internet data, 
such as "pits", spikes, square wave function graphs, clipping on some 
waveforms, etc.

This is not limited to MFN.  I have observed this on other similiar types of 
Sundry network data collection systems.

It is not easy to see HOW BAD the problem is with these Sundry data 
collection systems, UNTIL you expand the MRTG graph.  Once this is done, 
then you can really see how bad the integrity of the collected data really 
is.  A small MRTG graph really masks the problems associated with the data 
which is being displayed.  With a larger graph, you definately see the 
problems associated with todays Sundry systems.

As there is no way to really verify the QUALITY or INTEGRITY of the data 
being displayed, then I submit as fact, that what is being shown here is 
really in a grey area, at best.

So who really knows how correct, the data which is being displayed on the 
MFN home page is really is ?

Cause with the clipping, spiking, pits, & squarewave graphs, small graphing 
scale being shown, definately, I have my doubts ...

One would also wonder, that if this data collection system is used by MFN to 
generate bills for customers of MFN who are charged by the Megabyte, what 
these customers bills look like & HOW accurate these bills really are...

Regards,

Mike Martin.
