### Issue Details

Previously, after a routing optimization by the AdGuard team, latency from my ISP (Azfiber, Azerbaijan) to AdGuard DNS was around 63 ms.

Recently, the latency increased significantly.

The automatically assigned AdGuard DNS Free servers (94.140.14.49 and 94.140.14.59) both consistently respond with approximately 265–275 ms latency.

The issue is persistent and reproducible.

### Expected Behavior

Traffic from Azfiber (Azerbaijan) should be routed to the nearest AdGuard Anycast PoP with latency similar to the previous 63 ms.

### Actual Behavior

AdGuard DNS Free

94.140.14.49: ~265–275 ms
94.140.14.59: ~265–275 ms

Packet loss: 0%

For comparison:

Cloudflare (1.1.1.1): ~13 ms
Google DNS (8.8.8.8): ~46–52 ms

### Screenshots

### Additional Information

This worked correctly before.

After a previous routing optimization, latency was approximately 63 ms from the same ISP.

It now appears that the Anycast routing has regressed.
