traceroute and ping response times are just the indication how fast the management board on a particular router is able to send ICMP packets. If the management board is busy, it doesn't mean that the traffic is affected.

so, it needs a more detailed investigation with your provider, and most probably the problem lays outside of your ISP's control. Maybe some intermediate link somewhere is oversaturated, but that's not going to be changed at free will.

You can only get guaranteed throughput if you buy an end-to-end business connectivity service, but that's going to cost you an arm and a leg.

Subject: [swinog] Swisscom VDSL -> TELIA -> USA problem
Hi

a customer got problems with an application (trading tool) downloading from a server in the USA  (206.106.137.3). A traceroute below.

Responsetime of hop 12 (80.91.251.98) is much higher than hop 11 (80.91.249.113) and a ping test did show lost packets on hop 12 but not on hop 11.

the same application runs fine with a http proxy at LayerOne (init7), a proxy on a hosteurope vps or on a Cablecom connection.

Is this the right place to report such a problem and aksing for help?

Thank you!
