About Thailand IX

The Origin of Thai Internet


In the beginning, Internet users in Thailand mainly accessed overseas content, especially from The USA, European countries, Hongkong, and Singapore, which required an international connection gateway to access those content. The content exchange from Thailand’s users had to switch abroad before returning to Thailand since there was no domestic Internet exchange. This affected the high cost of the internet service fees, yet the content accessibility was ineffective because of the higher latency when exchanging data abroad.

Consequently, CAT Telecom Public Company Limited (CAT Telecom), the primary internet service provider, established National Internet Exchange (NIX) in 1995 as the Internet exchange point for domestic Internet traffic. Having NIX led to the data being exchanged more effectively with lower latency time and cost reduction for international internet connections.

Our Data Center

Thailand IX (TH-IX) was originally named CAT NIX (CAT National Internet Exchange) to provide Internet exchange service for users in Thailand by offering a Layer 3 network under the supervision of CAT Telecom Public Company Limited (CAT Telecom). Later, the service was changed to a layer 2 network in 2018, renaming the service as Thailand IX (TH-IX).

Presently, CAT Telecom Public Company Limited (CAT Telecom) was merged with TOT Public Company Limited and changed to National Telecom Public Company Limited (NTPLC). However, Thailand IX (TH-IX) is still under the supervision of a former CAT Telecom Public Company Limited (CAT Telecom).
