Thread: some websites opening slowly using even open dns

i'm facing a strange issue for the last few days, some of the websites r opening very slowly or not opening at all for example google, yahoo when i try later they seem to open without any problem. i have checked the computer for virus/spyware and reinstalled win xp. i am using open dns servers. no matter what i try the result is still the same.

modem: nokia siemens
mode: bridge
snrk above 20 for download
avg broadband speed 1 mbps

please help me find the cause n solution

the problem seems to be on BSNL's side.i too faced this problem where google opens very slow or not at all at certain times but back to normal after some time.
