I've noticed during my most recent stay here in Thailand that internet works much worse than before (I've been here for a total of over 2 years). I am considering to buy a long-term visa for a considerable amount of money, but hesitate as I know the government here is about to implement a Great Firewall of Thailand.
I don't know to what degree their Great Firewall of Thailand will affect my work online, and as I am very dependent of reasonable fast internet (like it was halft a year ago) for my work and other dealings I risk to pay a lot of money for this visa only to very soon be stuck with internet that I will not be able to work on.
I found this posting about it:
I lived 5 years in China, and even though internet was slow it worked fairly well. I used VPN to be able to visit blocket sites also. But it was quite stable all the time. What I am afraid of with Thailands Great Firewall is that it will slow down internet even more than in China, and that it will actually be worse than in China. In China, it was go-able, it worked. But less than that would not work for me, and that's the risk with the new Great Firewall of Thailand.
