Hi,

I was wondering a bit about the Google cache, so i went to youtube, and 
clicked a movie.

While the page was loading, i saw the name Bhartel as one of the servers that 
it was loading data from, so i opened the source of the page, and looked for 
that word, as Bhartel is the upstream provider of my ISP. I found this server

o-o.preferred.bharti-bom1.v5.lscache3.c.youtube.com

A traceroute to that server shows it is probably somewhere in India at about 
400ms from where I am.

Does that mean my ISP is not using the google cache at UTL, or was I just not 
lucky today? Or was my test just flawed? If so, how can i test if i get my 
youtube videos from the UTL gcache? And what servernames do other people (in 
uganda) see when they load a utube video? 

I clicked a random movie for my test, i happened to be this one 
http://www.youtube.com/watch?v=g7xQBNngzC8&feature=relmfu

btw, that cache seems to be doing its job, UTL is pushing 30Mb/s through the 
UIXP, quite impressive, that is about 6 times more than before they started 
sharing the cache. You can see the stats of the Ugandan internet here 
http://stats.uixp.co.ug/

Here is the traceroute.

bom1.v5.lscache3.c.youtube.com
