According to this post from FACT’s blog.

Today I experienced it myself, while I’m searching for a good coffee shop in Singapore. I found TheCoffeeJournal’s blog on Google and when I clicked the link, I suddenly see this page.

It says “Your access to this website is rejected by TOT Corporation because of it contains inappropriate contents, words or photos which cannot be accepted by Thai people.”

AFAIK, those contents are only available on Youtube and other online video services, so I don’t know why they blocked Wordpress.com

Anyway, when I tried to access TheCoffeeJournal again in an hour later, I can uninterruptedly access it, weird… -”-
