Some of the PINGS are posted there too! The traceroutes are used to back up the PINGs, and show the routes like 2 hops to the USA that all contribute to the latency.

Certanly the peerings I´m aware of are not used for voice traffic and usually QoS is not implemented on intercarrier Internet traffic.
Latency should be measured using end-to-end ping because intermediate times shown by traceroute are not accurate. This is related to the way routers process packets when TTL reaches zero value and ICMP TTL exceed message is created. Some routers are configured to avoid sending those messages and in many cases intermediate mpls routers are not shown at all on a traceroute.

Javier Salazar,

I disagree with your analogy of the Blog vs Peering. First if a page were inaccessible I would take steps to ensure I did not have a DNS issue and would probably check the accessibility of that page from another location. If you oversimplify that which you do to such a degree, it is really no wonder you do not understand the real issues as indicated below.

As for internet peering, those traceroutes posted here are only a FEW OF MANY traceroutes I have performed from many locations. Many of these peering arrangements are most probably filled with telephone traffic that is having some form of QOS applied and therefore receiving priority on those interconnections. If those interconnects are tied up with telephone traffic they are no longer viable internet peering routes!

Your case of Avantel/Telmex obviously is the EXCEPTION, and not the rule, and you still have abnormally high latency indicated in that traceroute which exemplifies the peering saturation issue! There is no excuse for that kind of latency on any "domestic" connection.

First: The presentation you are referring o was a personal made by me (Javier Salazar) not a LACNIC one.
Second: I personally made some of those peerings, so you cannot say is not true. Is like somebody saying that you don´t have a blog just because he canot access it.
Third: Here you can see a traceroute from Telmex DSL to Avantel.

You can clearly see the peering here.

It could be that some ISPs don't have peering as they should nor with enough bandwidth, nor with everybody. I suggest that you made some tests from different ISPs before expressing an opinion that obviously is not well documented.
