Thank you Michael, for throwing light into this. Yes, I see, Sabri and me are on two different rails, one leading north, the other one leading east. I hope Sabri still has got all his hairs. I am counting mine now. Kind regards and thank you again, Peter Dambier Michael.Dillon@btradianz.com wrote:

Your own traceroute clearly shows that your host is not directly connected to the AMS-IX. Nor does the KPN datacenter it resides in. The AMS-IX has 4 datacenters where members can place equipment which can be directly connected to the AMS-IX:
- GlobalSwitch; - Sara; - Nikhef; - Telecity2, Kuiperbergerweg;
Every statement otherwise is bogus, nonsense, crap or whatever term you prefer to use for this.
This is a good example of a useless argument caused when one person is speaking from a customer viewpoint and one customer is speaking from an operator viewpoint.
Assume that there is an ISP X with a data center in Germany and a colocated rack at Nikhef. They peer directly with many other providers through AMS-IX from their Nikhef location. Customer Q comes along and places a server in their data centre in Germany because he needs to serve his users both in Germany and in his chain of hotels throughout Holland. His network people assure him that the server is connected directly to AMS-IX because that is what their traceroutes say.
Of course, we know better. We know that the server is connected directly to ISP X and indirectly to AMS-IX because we are used to being particular about which operator owns each hop. But the customer Q doesn't see the hops in network X. To him, they are invisible because they are his HOME network. Customers don't see themselves as network operators and therefore they often think of their ISP's network as their own.
So who is right? Peter? Sabri? Both? My opionion is that neither of them is right because they both failed to understand what the real problem is and they both failed to take the correct steps to solve the problem. As it happens, this was a very, very basic network issue which does not need to be discussed on NANOG at all.
