They are lending it to BT.

You'll need to be a bit of a routing bod for this.

I'm unsure if this is actually intentional. Seems rather odd for traffic from Level3 to BT to go via Virgin Media.

As far as I know, VM provide backbones between data centres etc and not just residential/business BB?

This is something quite different from offering optical transport or point to point links.

I don't know, one gaming server i used to rent routed through Virginmedia from pretty much any service provider

im pretty sure they have backbone linsk including direct links, there one with teh bbc so wouldnt surpise if they have some with bt end of the day it probally better and possible cheaper for them than maybe have there own link tha tmight currently exist

You're both missing the point.

A lot of difference between a gaming provider (one did indeed use VM for transit) and this.

Look at the traceroute again.

Does it matter? as long as everything works!:)

I don't remember saying there was a fault. It was a discussion starter, it's good to have a discussion every now and then rather than just fault reports :)

EDIT: It does matter to VM though, trust me ;)

At first glance, it would appear that someone at Level 3 mucked up the routing somewhere.

Ignitionnet
16-05-2010, 18:18
Nothing to do with Level3's configurations.

Probably a fault somewhere caused a reroute through what was available and if that is VM then so be it.. How do people think that the internet gets from one side of the world to another or even across the country..and the simple fact that the routes are sometimes not static but depend on being fault free and capacity enabled.. ;)

:rolleyes:

Mine is the same not that I understand it. Does it affect us in anyway? whats level 3? Would this explain my codewords ( lol just a joke ;) )

Doesn't affect customers. I just, perhaps mistakenly, thought that there would be people who would understand the reference.

I'll let the thread die on that note I think. :)

Oh wow, even though I wasn;t asking for your guidance I really do feel the need to ignore it anyway.. ;) :p: :D

I was talking about the major routing backbones that companies put in and then lease the space to other companies that need use of the pipes.. If someones usual point to point develops a fault then normally it get rerouted through whoever has space up for offer.. Mind you last time I got involved in anything like that I was working for DEC and sys admining on PDP 11/750's and 6000 series Vax..

Nah I'm good, I spoke with a guy who got what I was talking about and found some more instances of things like this, per previous the thread can go to sleep as far as I go :)

For fear of getting ridicule from Igni I should keep away. But ....

Routing tables don't happen by accident. Could this have anything to do with the so-called 'fix' VM is claiming for World of Warcraft latency issues?

Chrysalis

I dont see whats so weird about it.

VM peer with various people which means their peers can use that bandwidth for routing traffic.

The route ignition posted didnt seem optimal but there may have been a fiber cut somewhere at the time.

Could it be a BGP aberration?
