Re: [nznog] Objective assessment of 'the Internet is slow' complaints

You can't get to every node in the path, but you can sometimes traceroute back from a remote point using some of the looking glasses internationally. http://www.traceroute.org/ More NZ based looking glasses in the core of ISP networks would be very very useful though (hint, hint...)

Have you looked at the timeline feature hidden in Chrome's developer tools?

It is designed to allow web developers to tune the loading speed of their web pages but may provide a reliable way to measure request latency and load time.

In my role at Massey University, I am often asked to investigate complaints from our Help Desk of a 'the Internet is slow' nature. We are finding this increasingly difficult to do in any meaningful way. Massey is peered at WIX, PNIX and APE we have two Internet peers and have multiple paths to them and they both have multiple upstream providers.

Simply ping testing for latency/connectivity doesn't really provide much of an insight, traceroute tells us where outbound packets went and which hops are 'slow' but doesn't indicate the return path. Most of our customers equate Website == Internet, so the responsiveness of a destination seems to also be an important consideration.

I am assuming that most ISPs have Help Desk calls of a similar nature. How does one substantiate or refute such complaints, pro-actively identify 'slowness/congestion' ? Evidence collected by 'tools' needs to be defensible when responding to our 'customers'.

Any pointers to how I can do this better would be appreciated.
