Hello,
There has been some routing glitch in the F root server instance running in Chennai, India by niXi AS 24049.
Govt. owned BSNL AS9829 routers are not hearing any BGP announcements and thus F root does not works at all on BSNL.
anurag@laptop ~ $ traceroute f.root-servers.net -A

I have been hosting RIPE Probe #1032 and here is F Root connectivity data from proble:
As we can see root server is not accessible at all from Jan and even in Nov, Dec last year it was available with over 300ms latency which indicates network was not using Chennai anycast node since latency between this test probe placed in Haryana (North India) and Chennai (South India) should be around 70ms.
