Do all NTL newsserver names point to same server?

Default Do all NTL newsserver names point to same server?

Hiya Sandi.
Please don't add crossposts that have been removed, especially
when the groups aren't carried on my local news feed


Ponder, apologies for that. I had not intended to offend. I had
originally considered the "home networking" group but thought I then
removed it. Guess I left it in by mistake.

OTOH "uk.telecom.broadband" seems quite relevant.

ISTR that if a newserver does not carry a group then that newsserver
should still be able to pass the posting request to its peer servers
which will try and make sure the message is correctly sent. In fact
someone once told me that this requirement/suggestion was stated in
one of the RFCs.

I know some servers don't adhere to this (eg Astra). But NTL's own
newsservers carry both ntl.discussion.broadband.cm and
uk.telecom.broadband.

Does this mean that the correct name for NTL's newsserver is
now "news.ntli.net".


Seems that way.



And that "news.ntli.net" is the best name to use as they will
load balance the rear-end servers to provide "news.ntli.net"
with the most even service?


Doesn't make a difference which one you use, they're all the
same in reality


I am not entirely sure those names for NTL's newsservers are the
actually same because they seem to resolve to different IP addresses.
Maybe the lookup software you used was cleverer than the one I used
with the result that I got just one IP address for each server (but
there may have been more IP addresses).

QUESTION: What lookup tool are you using?

maybe someone else who knows NTLs newsservers can also comment?

of reference to the IP info.

----------- ORIGINAL POST ---------------

I can only find these three different IP addresses for NTL
Usenet servers:

news.cable.ntl.com
= [ 194.168.222.120 ] = [ newsfe1-gui.server.ntli.net ]
news.virgin.net
= [ 194.168.222.120 ] = [ newsfe1-gui.server.ntli.net ]
news.tesco.net
= [ 194.168.222.120 ] = [ newsfe1-gui.server.ntli.net ]


news.ntlworld.com
= [ 62.253.162.202 ] = [ newsfe2-win.server.ntli.net ]


text.news.ntlworld.com
= [ 194.168.222.122 ] = [ newsfe3-gui.server.ntli.net ]
news.cable.ntlworld.com
= [ 194.168.222.122 ] = [ newsfe3-gui.server.ntli.net ]

---------------

However by extrapolation of the number sequence in the server
name [ newsfe3-gui.server.ntli.net ] I get these working servers:

[ newsfe4-gui.server.ntli.net ] = [ 194.168.222.123 ]
[ newsfe5-gui.server.ntli.net ] = [ 194.168.222.124 ]
[ newsfe6-gui.server.ntli.net ] = [ 194.168.222.125 ]
[ newsfe7-gui.server.ntli.net ] = [ 194.168.222.126 ]

---------------

Are all these 7 actually separate servers?

Is anyone able to tell how fast the different servers are?

Maybe someone has an automated PING utility to see which ones are
fatsest at different times of the day to see which ones cope best
with peak loads.
