First and foremost, this page was inspired by the work of Jim Baughman, who created the original Austin Cable Modem Analysis. Using modified versions of his perl scripts, these pages currently evaluate Grande Communication's cable modem service at regular intervals throughout the day. You will see graphs of throughput and latency for connections between my home computer and another in the utexas.edu domain.

I first had cable modem service installed by Time Warner in February of 2000, and even before the service was turned on I had perused the Austin Cable Modem Analysis website to see what sort of performance I could expect. Then, once I had my cable modem, I started wondering how my network statistics compared to his (since we are on different "neighborhoods"). Especially given the poor UT<->RR connectivity during the first two weeks of my service I started doing little things like pings and traceroutes, until finally I just asked Jim for his tools. Thanks to his work and generosity, now I can offer a similar service to the community. In 2008 I moved to another part of Austin, and switched to Grande based on all the things I'd heard about better service and pricing, so information since that date reflects Grande's 12Mb/s service.

What you will see here are the results of the network tests between the following machines:

If anyone has any questions about the tools used to create the statistics, you're probably better off emailing Jim Baughman, but you can also email me at shanew@gslis.utexas.edu
