AdGuard DNS not using the nearest server — Singapore

Hi, I’m located in Singapore but I’m being routed to Japan servers instead.

Not sure how networking work, and how geographically it deem Japan server as having the least network hops. Here's my traceroute results;

I'm also experiencing similar issues. I am located in NY and there's an Adguard DNS resolver close to me however, I'm being routed to a server in Japan which is causing significant latency issues.

I live in NY as well and am being routed to Japan! The routing that AdGuard does is completely F'ed up, glad to know I am not alone though. Their decision to use shortest number of hops is fundamentally flawed. Yes, 3 hops at 200 ms (with timeouts mind you) is shorter than 10 hops at 10 ms but that doesn't make it faster.

Hello, this is an old issue with adguard dns, sometimes the routing is working well but now, since the day they changed to the news addresses, i have still the same problem. The place I live in is in Europe, I use a dual stack ipv4/ipv6 connection, from my home i can ping Frankfurt 22ms, Amsterdam 12ms, Paris 14ms, London 13ms..my ipv6 dns requests are redirected to Amsterdam with 8 hops, (this is great) BUT all my ipv4 dns requests are redirected to USA 89ms 11 hops.. This is happening with my belgian/dutch ISP, i have no issue with my mobile provider..

Update: As of recent, I'm being routed to Amsterdam (dns2-dp-ams-2). I'm still located in NY.

Is there a way to choose your own server location?

As per my knowledge, route taken by ip packets from one destination to another completely depends on original internet server provider of tier-1 isp that u r connected to. It's not Adguard's fault. Report routing errors to isp.

I am located in India. Nearest adguard dns is Singapore. But i always got connected to NY server. So i complained to local isp who in turn uses Tata Communication as tier-1 isp, and said "ask Tata to change routing table". Within 1 week tier-1 isp of India changed their routing tables and the shortest path to SG got selected. Enjoying lower latency now

Impressive that Tata took into account your request. Won't happen here is Europe.

I have some issues with Google and YTM because their routing table are wrong but their so called specialists told me nothing was wrong on their side. Such arrogant Google engeneers.
