i am also facing the same issue in pune. For me below sites are not working ,Redbus.inRediff - mail box Adobe - pages are loading but no able to downloadit's totally frustrating,few days back i wanted book bus tickets urgently and tried redbus several times but failed , initially i thought problem is with site. But then when i checked with some of my friends using other networks,then only confirmed it's issue with my bsnl modem only. Besides this many sites are loading but not getting properly loaded ,even in broadbandforum am facing this issue .But for me yahoo mail is working fine.In addition speed reduced a lot since last few weeks,infact am using only limited data plan only still not able to download anything. if anybody manage to talk to CSC please update about this issue.
Few websites not opening with BSNL 3g

Well I worked around a bit to solve the issues with few sites. Please try and confirm if this is working for others also or not. 1. Run command prompt using admin privilege.2.

I changed the mtu using netsh command in windows 7 to 1400 and now i can access hotmail, ignou, speedtest and many other sites listed here except paypal.
Procedure for changing mtu
to see what interfaces you have on your computer, type
netsh interface ipv4 show subinterfaces
to change the mtu, type
netsh interface ipv4 set subinterface "ppp" mtu=nnnn store=persistent
where
ppp is the name of the network connection on your computer, from the list obtained above. (generally its 3g modem)
nnnn is the desired value for mtu.
Reboot after making the change.
Ps : Please note the default value for 3g modem, just in case you need to revert it back.
yes changing mTu solve this problem so everyone use this its really work thanks bro.....

Problem here is not with speed , few sites were not at all loading.

Good work priyaiyer. Looks like fragmentation issue with some BSNL gateway. By tracing route, I can see that packets of sites that do not work go through a different path than the sites that work.
For XP users, look at this site for changing MTU to 578 (in hexadecimal) or 1400 (in decimal). How to manually set the MTU size in Windows XP 2003 2000 Vista | Windows Reference. Be sure to restart the PC after setting MTU.
