DNS Landscape in Thailand
Thailand has strong internet infrastructure with major ISPs like True Online, AIS, 3BB, and TOT. Bangkok has excellent fiber coverage and DNS peering is generally good. 3BB and True both offer decent ISP DNS, but public resolvers still provide better performance. Thai users tend to be early adopters of technology and many have already switched to public DNS.
Cloudflare has data center presence in Thailand, making it the top choice. Google DNS also performs well. The difference between public DNS and ISP DNS in Thailand is noticeable but not as dramatic as in developing markets.
