Traffic between two hosts located in India is usually routed through
US or European networks. 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 126.96.36.199, says that the address belongs to
UUNET Technologies, Inc., VA, US. The address 188.8.131.52 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
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.

There are a few Indian shops which do sell inexpensive FreeBSD and
GNU/Linux CD-ROMs --- costing about USD 4.00 for three CDs.
