hmmm... this could be a solution, but from what source does uunet
generate this filter-list ?
The Ripe-Database contains this route object:
route: 151.189.0.0/16
descr: CALLISTO
origin: AS6751
notify: guardian at seicom.net
notify: guardian at germany.net
mnt-by: AS6751-MNT
changed: wh at seicom.net 19980126
source: RIPE

yes sure... but the question is, why did uunet change their filters
within the last days without action from us or our customer ?
And the magic is, the rest of 151.189.0.0 (e.g 151.189.10.0) is seen
via 151.189.0.0/16...

great !, 2 Tickets are already open, and no response from uunet. A
company who is about to control 60% of the us-internet market can
manipulate a lot of things and make a lot of money!.
I would say at least 50% of the german internet isps are connected
to uunet in Frankfurt. With their wrong announcement, their customers
got germany traffic over a internation link and paid for this. Whom did
they pay ? right uunet.... i think this wasnt a wanted effect currently
but it shows what could happen and who gets money for these mistakes.
I dont care this /24 in the us, because from our view it makes no
difference, but for the german isps it made a big difference.
We corrected it by announcing this /24 at mae-ffm, inxs and de-cix but
it cant be right that we have to change our announcement because the
world-leading isp has wrong filters.
And calling uunet in Frankfurt leads into a 10-minute voice claiming
your call is important to us... bla bla bla...
i think we gonna sent all 30seconds a mail to help at uu.net :-) hopefully
their tracking systems beaks down and they are pleased to answer :-)
or should we announce 198.6.1.0/24 and route it to /dev/nul...
or should we dig a hole and put our uu.net problems there into ....
Winfried - frustrated
PS: even a mail from the german uu.net people (thanks to them!) is stil
without response...
