That is certainly not my (and many others, I'm sure) understanding of
the Usenet network. It may have been a star network in the very early
days but it is now, and has for quite a while been described as a mesh
network.

Ok, first, the microsoft.public.* newsgroups are not usenet.

Second, call it what it want, it is still the same thing. A mesh is
just a form of a star network.

No matter what you can wish to call it, it requires coordination and
each node knowing who are their Uplinks and Downlinks which is what
experts in the mail distribution market, who still run the show, know
it as. Otherwise you will have redundancy (and hence duplicity).

An uplink is who you send data too, and downlink is who you get data from.

Now, in a mesh, redundancy may be part of the expectation with
duplicity considered a lower overhead operation then it was in other
days where hardware did did not allow for such low efficiency however
it still needed to be checked.

In a well coordinated network, to minimize duplicity, the nodes are
usually going to go to a more centralize hub (lets call it MAIN). If
the Nodes are going to also serve as HUBS for others, then they better
have dupe checking because they don't KNOW if their own nodes are also
using the MAIN hub.

In general, old and current, every node has a list of remote host they
will connect too to IMPORT and EXPORT information.

If you wish to see the PATH a messge takes from any server, see the
Path: header in a newsgroup article.

Viewing your message from the Microsoft NNTP server, I see:

Path: TK2MSFTNGP01.phx.gbl!TK2MSFTNGP06.phx.gbl

That means that it was posted at

TK2MSFTNGP06.phx.gbl

but it was also imported to:

TK2MSFTNGP01.phx.gbl

You can tell it was posted at TK2MSFTNGP06.phx.gbl because of the
message-ID: header:

Message-ID: <uSSuHig7KHA.4208(a)TK2MSFTNGP06.phx.gbl>

Now if I go to google groups and see your message from there, I see
(all one line)

Path: g2news1.google.com!
news1.google.com!
news.glorb.com!
feeder.erje.net!
weretis.net!
feeder1.news.weretis.net!
TK2MSFTNGP01.phx.gbl!
TK2MSFTNGP06.phx.gbl

Starting from the bottom, the feeder1.news.weretis.net! server it
pulled from Microsoft TK2MSFTNGP01.phx.gbl! and it was gated thru a
number of 5 additional servers.

Well, #1 once the MS servers goes down, Google will not be able to
pull from TK2MSFTNGP01.phx.gbl! It will have find some thing else.

#2, you won't have MS server to post, and if you found another, you
don't know if Google will be pulling from it or that your Serer will
be posting to GOOGLE.

So no matter want you wish to call it, there is is a "backbone"
concept where there is a main hub who is normally known as the OWNER
of the newsgroup.

In regards to USENET, this is different issue. This is in industry
sponsored backbone. Not one company ones it. Its like a DNS.
Everyone has it access to add and remove from it. As long as you have
have primary uplink you can act as a primary server as well.

Anyway, with usenet, long ago, we requested an alt.* group for usenet,
It still exist:

alt.bbs.wildcat

We abandoned it long ago around 1997 when it became a high volume of
spam for us and the anonymous dirt was not something we wanted to
bother with our customers with when it was gated into our support
avenues.

The only reason we had no problem abandoning it was because it wasn't
our NEWSGROUP. We were not the main hub for it.

Thats not the case here with Microsoft.* newsgroup. These are not
usenet groups. The main hub was Microsoft where others pulled from.

Now, if someone were to migrate all the microsoft.public.* groups into
usenet groups, then you and Jochen would be correct, it wouldn't
matter if the Microsoft NNTP servers goes down because they would be
just a node off the backbone, not the main hub for it.

Hey, who knows, Maybe Google's answer to this Microsoft dropping of
their NNTP server would be to announce their own services to be
available. But they don't want people off the web for the same reason
Microsoft wants people to use the web. :)

Gee, I wonder why Microsoft themselves refer to them as Usenet groups...

People post to the groups from all kinds of different servers, when the
Microsoft servers are down these other servers still synchronize between
themselves without any problem and these folks who post on other servers
can still post and read without the intermediary of Microsoft servers.
We have often seen this in the past when outages of a few hours or more
at the Microsoft servers have happened and some of us use other servers
to keep on posting, when the Microsoft servers come back only line they
then "catch-up" and then all the posts show up many hours latter on
these servers. This is obvious enough when you use non Microsoft
servers to read the posts in Microsoft groups, all kinds of posts which
have not made it to the MS servers, or posts which have been removed
from the MS servers are on the other servers for all to see and read.

Most probably you won't be able to move to anywhere else; not even
on forums because Microsoft hasn't got any plans to open forums
for Windows XP and earlier technology. Somebody suggested that
you can go to other P2P newsgroups like Google or aioe.org. This
again won't be possible because microsoft may force them to close
their newsgroups bearing Micro$hit name.

The only alternative I can think of is for somebody to organize a
group of about 10 individuals to come together and start their own
newsgroups to be financed by advertising and volunteers. I am
willing to put my name forward for this project provided there are
individuals who have some basic knowledge of hosting NNTPs which
can be expanded further as time goes by. I am good at programming
and developing websites using Java, Javascript and ASP and perhaps
some networking skills and SQL servers. that is all I know at
present.

Unfortunately, another case of Microsoft creating user confusion in
this regard.

Microsoft.public.* are *not* part of the usenet backbone newsgroup
listing nor backbone stream.

Check it out yourself. If you have access to a major ISP where you
have a high trunk line backwidth such as a T1 or T3, you will see that
the usenet feed newsgroup listing does not include microsoft.public.*

If a smaller ISP is showing microsoft.public.*, then they are directly
or indirectly going to Microsoft servers and are MERGING it with the
usenet listing. But they are two different sources of feeds.

All that will change one MS pulls the plug from the wall.

While you might find another site that keeps the newsgroups and they
still remain relatively active, that is only because the site itself
have become the MAIN source for others to feed into - a large part of
the chain. But those chains that feed off Microsoft only are lost
unless they feed into someone else.
