That's possible, but unlikely.  Beartooth just started trying motzerella 
a few days ago, so he just downloaded their list of groups a few days 
ago.  They'd have had to have quit carrying the group in that time, and I 
don't find that likely.

The more likely case might be that the motzerella server is having 
problems and is listing headers for messages it doesn't have and losing 
its own groups.

I don't know what news server software it's running, but that sounds a 
lot like some of the problems highwinds-media, the outsourced provider 
Cox (my ISP) is using, has had.  And other ISPs and providers I've been 
with over the years, running the same highwinds software, have had 
similar problems.  Apparently, when that software is configured and 
running perfectly, it has some of the best performance numbers in the 
business, but it's just terribly difficult to keep it configured just 
right, and normal changes in usage patterns move even previously properly 
configured and peak performing servers out of their zone within months, 
to the point that my experience has been they typically spend perhaps two 
months working and four months sort of working, cycling maybe twice a 
year, so a site is lucky to get good service out of them for four months 
out of the year.  The rest of the time they kind of limp along, one bug 
after another, tweaking this and that and replacing components here and 
there, until a few months later everything clicks again and they're back 
at peak performance for another month or two.

Other server software apparently has much lower peak bytes and articles 
per hour served numbers, meaning on paper more servers are needed to 
serve the same number of people, but it's easier to maintain at peak 
performance so there's not quite the same ups and downs.  Some of this 
other software actually runs on commodity x86 hardware, not the "big 
iron" Sun servers Highwinds software runs on, but it can take fifty or a 
hundred such servers to handle the job 3-5 Highwinds servers can handle 
with ease, but only when the Highwinds servers are at peak performance, 
which as I said my experience as a user suggests they really aren't, more 
of the time than they are.  But there's a reason Google runs reasonably 
off the shelf commodity hardware... and does so good at it, even if at 
their size they're changing out several bad servers (out of tens of 
thousands) a day.

The problem with that is that I hadn't thought motzerella was that big a 
service, given the cost of big iron and highwinds software and the fact 
that motzerella is free.  So I just don't know.

Meanwhile, I'm almost getting a hankerin' to sign up and check motzerella 
out myself, if only just to see what behavior I see here, possibly trying 
the same messages beartooth is having problems with.  If necessary, I 
could then run a telnet session, and see exactly what the transactions 
are doing on the wire.  Plus then I could see what servers they /are/ 
running.
