Hi All,For the past two three days I have been experiencing a few problems like server time-outs on yahoo, Google, India-Forums.com and a host of other web-sites. Initially I thought this might be a server problem with yahoo or google ( a DoS attack or sumthing) but when this happened with a host of other sites, I smelt sumthing fishy.i tried pinging the mtnl server and others observing a lot of packet loss. (100% in sum cases)can any one help me out.tejas

mtnl websites r down 90% of the time ....so no use pinging them u'll most probably get request timed out on em and since the ping to the dns was ok ....there seems to be no prob with ur dns. try using other dns servers and see if the problem persists.

Packet loss can happen due to Network congestion. Bandwidth undercapacity issue at the DSLAM.

If ping to dns server is ok then it cannot be a line problem.
Code:
Ping (your dns server IP)  -t
Ideally there shouldn't be any packet loss at all. Then try pingging other websites. If you see packet loss of more than 1-2% then its a clear case of network congestion.
