For example, here is the output of `traceroute' from a host in Allahabad in the North, to Bombay in the West of India.

A `whois' lookup for 208.192.183.149, says that the address belongs to UUNET Technologies, Inc., VA, US. The address 134.159.128.42 belongs to Reach Networks HK Ltd, Hong Kong. As I understand it, this means that traffic from Allahabad goes to the US, and then to Hong Kong, before it reaches Bombay. Therefore, the geographical proximity of two hosts within India does not imply their proximity on the Internet. In addition to such routing troubles, most Indian sites suffer from severe bandwidth paucity. A few years ago, an Indian research institute set up a mirror of the electronic preprint repository `arXiv.org'. However, because of routing anomalies --- and because the Indian site does not have as much bandwidth as the master `arXiv.org' site in the US --- many users find that it is faster to download papers from the master site, than from the Indian mirror. I think that would be the case also with a FreeBSD mirror in India. This could be one reason why there are no such mirrors. Another could be the fact that very few Indians use UNIX, or its clones --- and those who do mostly use GNU/Linux. > Additionally, a mirror site in India could burn CDs locally and hand > them out There are a few Indian shops which do sell inexpensive FreeBSD and GNU/Linux CD-ROMs --- costing about USD 4.00 for three CDs.
