Concern about gTLD servers in India

Just looked at j root in detail.


Unfortunately not much of traffic is going to J root. BSNL along with its
main upstream providers Tata & Airtel - all picking outside routes. Tata
AS4755 is taking directly to AS6453 while AS6453 is passing to NTT in
London which is next taking back to Japan and then going to HK anycasted
node (yeah head shake routing!).


Here's a view:

Path via NTT in all cases.

So Mumbai - London - Japan - HongKong. Very likely because of same old
problem I mentioned - Tata peers with NTT in London but not Japan.

And situation for Airtel isn't better at all for J root. Instead of picking
NTT, they are using Packnet/AsiaNetcom because Packnet is likely a client
of Hurricane Electric and Airtel peers with HE.

Same problem applies on J gTLD server too. It might be having an instance
in India but since no link to local ISPs or niXi...everyone hears J root in
Hong Kong.



Anyone from Verisign or Indian ISPs here for onlist or offlist comments?

Again, I apologize for any wrong conclusions. I am still learning all this
stuff. Please excuse my ignorance and correct me if you find something.


Thanks
