Official word on the streets is that the social network censorship that happened a few days ago was due to ISP routers unable to handle the load since everyone is at home reading news. Riiiiiiiiiiiiiiiight. I believe you. And pigs can fly too.
Earlier when I thought this blog was also being blocked turned out to be that the government was blocking access to ghs.l.google.com, which is the address that Google Apps based services (including blogger.com) resolves to. However, since ghs.l.google.com is on a round robin DNS system, and they were only blocking some sets of IP's, so it appeared that the blocking is random and goes on and off. (And the government is using this as an excuse that the ISP's can't handle the load.) But this actually due to the fact that some IP's being blocked and some aren't. Facebook.com and other social networking sites were affected in the same way.
One of the mysteries I encountered at work is that some of my users when traveling to China to our subsidiary would have trouble accessing our Google Apps based mail, while others have no trouble whatsoever. This is quite difficult to debug when China is about 2,000 miles away.
Last month when I finally had a chance to go to China myself, the first thing I did after arriving and getting Internet access, was to open the company's email. ... and, nothing. A quick look proved that I was being blocked by the Great Firewall.
What does the Great Firewall have to do with the Thai government censorship? Turns out they both block ghs.l.google.com. However, there is a way to access Google's services, and that is through the google.com domain name itself. So, instead of going to, say, www.ivoidwarranties.com, which resolves to ghs.l.google.com, simply go to ivoidwarranties.blogspot.com, which resolves to blogspot.l.google.com.
Or in case of Google Apps, instead of going to, say, www.capothai.org, which was a case of the right hand blocking the left hand, simply go to sites.google.com/a/capothai.org/www
As of this writing, 18.104.22.168 is still blocked by the ICT, so hopefully this post will help.
