Thread: Unable to open many websites (DNS : Google)

From past 3-4 days, I am unable to open some websites. This is not because of BSNL DNS as I am using Google DNS. What can be possible reason?


Website which I am not able to open
www [dot] onebillionminds [dot] com
scheduleman[dot]org
and many more

Please help!

If you are on pppoe mode, change to dialer mode and check whether the sites open.

Check MTU setting in modem/router. Change to 1492. or lower.
Or
try TCP optimizer from speedguide.net.
or check your fiewall settings.
mention your modem/model/make/number.

Try Opera Turbo.

whether they understand the issue or not
why cannot people just shut up or say I don't know.

Will try to follow your advice and usually use quotes in my reply IF NEEDED.

Are you able to open up these websites by typing in the IP addresses?

You need to be more polite, buddy. Agree that some may just add some comments which "apparently" are of no value. But I have often observed that sometimes very silly mistakes are created.

To quote an instance of my own (entirely disconnected with the above issue):

I have Reliance Netconnect+. Recently my laptop was reformatted to upgrade the OS. When I installed the NC+ software again, I entered the wrong user-id (just two digits got interchanged). I was not able to connect. I even called the Reliance CC on that. They were also unable to find the problem (naturally). After a day, I realized my mistake and corrected the problem (which was never a problem to begin with).

So, while some suggestions may appear silly, sometimes even these work.

Following is Settings of my Modem

I even tried opendns, still I am not able to open some sites. Please help

Please see in your modem any box to change MTU to 1492.
Did you try tcp optimizer from speedguide.net. try default values and MTU etc.
