Title: RE: WorldComm Fiber Cut
Ah, but she didn't say she believed it. Just said where the data was...
Do we really need to verify what it shows? At best, it shows that they have spotty reporting. At worst, it shows rather severe reliability problems. Take your pick...

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.
