So maybe you are seeing these high peaks when Comcast can deliver a series of IP packets that are stored in their caches instead of being delivered from their customer's machines.
Sound logical .., that peak over 1000kB/s durated only a few seconds n reduce fast to about some tens of kB/s still very fast compared to mine about 12/13 kB/s. But the rate is more stabile than downloading from conventional mirror sites n maybe 3 hours faster on downloading a CD. I think it could be faster when more from downloader from this geographical site r participated at the sametime, I was seeing only temporal an IP with the same first 3 nurmber during downloading ..
