Narrow_Band_Minus 7 Report post Posted January 31, 2011 Hi , From last 2-3 days , when I am trying to launch google.com using my BSNL 3G connection , getting the following: ========================================================================================= About this page Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen? This page appears when Google automatically detects requests coming from your computer network which appear to be in violation of the Terms of Service. The block will expire shortly after those requests stop. In the meantime, solving the above CAPTCHA will let you continue to use our services. This traffic may have been sent by malicious software, a browser plug-in, or a script that sends automated requests. If you share your network connection, ask your administrator for help — a different computer using the same IP address may be responsible.

IP address: 218.248.84.93 Time: 2011-01-31T07:35:34Z URL: http://www.google.co.in/ ========================================================================================= There will be captcha. You need to enter that captcha to oppen up google. Any Idea why this error coming out ? Share this post Link to post Share on other sites
Arun 795 Report post Posted January 31, 2011 It is because your ISP (BSNL 3G) is assigning your PC with a shared IP address which is shared by many users at a time. Google has anti-DoS protection in place and when many users access Google using the same IP address it would detect the traffic as a possible DoS attack and hence it tries to block your access by showing up the error message. BSNL must be trying to cut their costs by assigning a shared IP for all users or maybe due to the scarcity of IPv4 addresses. They have to implement IPv6 and start providing dynamic non-shared IP for each user. I think BSNL also offers static IP address at a cost if you are looking for an immediate solution. It isn't Google alone that you will face issues with. Some files sharing websites like Rapidshare, Megaupload, etc. will also deny you access if other users are downloading at the same time using the same IP. Another issue is that BSNL harbors the most number of spammers (see: http://www.uceprotect.net/en/rblcheck.php ) and many mail servers will have the IPs blocked as well and you won't even be able to send email if the recipient mail server is using a blacklist that lists the IP as a spammer. The same applies for websites that use spam check database to prevent spammers from signing up as well (I hope "inception" is reading this ) 3 Share this post Link to post Share on other sites
