Hi, I have noticed that my TPG internet has a routing problem when accessing the website/server located in Thailand. The latency from other internet providers is around 120-140 ms. But the TPG internet is >250 ms. This problem happens with many servers located in Thailand, not just one. Here are the traceroutes.

And for reference, there is no latency problem when I use a VPN on TPG Internet. The traceroute from VPN is in the spoiler.
