Miscrosoft Edge began to repair DNS-over-HTTPS performance issues

by ·

Microsoft began testing and fixing performance issues in the DNS-over-HTTPS (DoH) function of Microsoft Edge and enabled the built-in DoH server list again.

DNS-over-HTTPS allows browsers to perform DNS resolution through an encrypted HTTPS connection, rather than through ordinary plain text DNS queries. Since some governments and ISPs monitor DNS traffic to block connections to websites, DoH will allow users to bypass censorship, prevent spoofing attacks, and increase privacy because their DNS requests are not so easily monitored.

Microsoft Edge added support for DNS-over-HTTPS (DoH) in version 86, but after users started reporting performance issues, it temporarily deleted the built-in DoH server list and the automatic upgrade logic based on the operating system DNS settings. Only manually providing the resolver URL is supported.

However, Microsoft has already begun testing the repair of DNS-over-HTTPS (DoH) performance issues, and users can now access the built-in DoH vendor list again in the latest Microsoft Edge Canary and Dev versions. The DoH providers currently provided are CleanBrowsing, Cloudflare (1.1.1.1), Quad9 (9.9.9.9), NextDNS, Google (Public DNS), and OpenDNS.

If the DNS service provider selected by the user does not support DoH, its DNS query will still use the ordinary DNS protocol. In addition, users can check whether DNS-over-HTTPS is working properly by visiting Cloudflare’s browsing experience security check page.
