Slow Access to Some Video Websites

If you find that accessing certain websites is slow when using AdGuardPrivate, it may be due to the following reasons:

ECS Support:

The free version of AdGuardPrivate does not support ECS (Extended Client Subnet) functionality. ECS is a DNS protocol extension that allows DNS servers to provide more accurate DNS responses based on the client’s network location. Many CDNs (Content Delivery Networks) use ECS to direct users to the nearest server, thereby improving speed. The free version servers are located in Shanghai and Hangzhou.

Impact:

  • Slower Speed: Without ECS, AdGuardPrivate may not be able to direct you to the optimal CDN server, resulting in slower speeds.
  • Inaccurate Geographic Location: You may be directed to a server that is farther away from you, increasing latency.

Solutions:

  • Upgrade to the Paid Version: The paid version of AdGuardPrivate supports ECS functionality, which can resolve this issue and improve speed.
  • Use Other DNS Servers: You can try using other DNS servers that support ECS.
