Strange. i use opendns and don't notice any lags with google.

BIND & pDNS are for *nix only machines, if you don't have a reason for one they aren't options.

This doesnt look good. why so many timeouts :ashamed:
 
Something is definitely wrong with google related sites on BSNL Broadband today. I have having problems opening google, gmail, youtube. Either they don't open and even if they do, its too slow :(
 
here is my traceroute to TE and google (via open DNS)

dude, i think you didn't see the smiley;) . i was hoping, if you were, id get 2 more DNS ip's of yer DNS numbers. :P

@greenie...
ok, i'm using OpenDNS and i haven't noticed any slowing down. but with BSNL DNS as primary ones, yes everything is almost slow. Here is what i did,

used OpenDNS as primary & secondary on my router, then again OpenDNS primary & secondary, BSNL ones as optionals on my systems.

If this resolves any problem, let us know.

Many ppl with NIB-I or NIB-II connection are complaining about they are not able to connect to some sites.sometimes it is google,micro$haft etc.

So the Solution is to change the MTU(Maximum Transmission Unit) to 1454 from 1500 or 1492.

In GNU/Linux , you can easily change by editing /etc/ppp/options file or /etc/ppp/peers/dsl-provider or /etc/network/interfaces or /etc/ppp/pppoe.conf file to add MTU value in format "mtu 1454" without quotes:ohyeah:

First try as root ,"ifconfig ppp0 down && ifconfig ppp0 up mtu 1454" to see the change!I was not able to access youtube and all(very slow).now it changed

In window$ ,I have no idea.apart from in cmd , "ipconfig /ALL" will show those values

but I saw this thread ,in broadbandforum :
