View Full Version : Slow speed & curious routing

My transfer rates are absolutely shocking, has been getting more and more so over the last week or two.

latest speedtest gives (for my 10Mb service):

Am not really too fussed about an upgrade to 20Mb, I just want something that resembles my original 10.

Curiously though, I have something in a trace route I have conducted which baffles me a bit; hopefully someone here a bit more knowledgable here can shed some light on it. The following trace is to a game/voice server based in Redbus data centre, London docklands.

Tracing route to kurak.pulsegaming.com [217.64.127.41]

over a maximum of 30 hops:

Trace complete.What jumps out at me is hop number 4. That to me looks like the hostname of a broadband customer? Am I being routed through someone elses home connection, or am I just misinterpratating the trace?

i'd say no, otherwise you'd see a ubr host before hop 4. it's more likely work has been done and they've changed IP allocations and are using an old customer range for routers etc and just not updated the DNS to reflect the changes

Oh, bugger. What a pile of mess.

That seems a very reasonable explanation, thanks :)

Hope the mess clears up soon though.

If you telnet to the strange IP you can see that it is a core device in Leciester (and that they havn't applied a correct port 23 access control list!!) :


C:\>telnet 82.3.32.237

Good work, am happily convinced now. Was fearing I was making someones already crippled internet in Luton act even slower ;)
