Just talked to Netvision Asakim support - He was knowlegable - ran `mtr` on his workstation and saw the packet loss.
He explained that "there is no problem" and that the core routers are dropping the ping packets based on the amount of load on the router. He explained that the router should only be dropping ICMP packets. I got to them by calling support ( 04-856-0550 ?) and telling them that there is a problem with their core network.
