Isn't this very old? I am sure I stumbled upon this while doing some research on a CDN project I was interested in about 5-years ago.
I would assume that CDN technology has progressed significantly since then.
The impression I got at the time, was that it wasn't maintained - as well as I would have liked. I could be mistaken, but that was the impression I got a few years ago.
"20 Aug 2012: We're still here! While active development has been stopped for a while, we continue to operate CoralCDN as an open, free service. It's now been running continuously for more than 8 years (since March 2004), and continues to get a few million users per day at last check. Enjoy continuing to use the service!"
»CoralCDN has been continuously operated since March 2004, running on 300-400 servers on the PlanetLab testbed, spread worldwide. As of 2011, it receives 25-50 million requests per day from a few million unique clients.«
In the beginning you had to add .nyud.net:8080 but it changed to the more convenient .nyud.net along the way.
