Quote:Microsoft is testing a fix for performance issues in Microsoft Edge’s DNS-over-HTTPS feature and has once again enabled a list of suggested DoH servers.
 
DNS-over-HTTPS (DoH) allows DNS resolution to be performed over an encrypted HTTPS connection rather than through normal plain text DNS lookups.
 
As some governments and ISPs block connections to sites by monitoring DNS traffic, DoH will allow users to bypass censorship, prevent spoofing attacks, and increase privacy as their DNS requests cannot be as easily monitored.
 
Microsoft Edge added support for DNS-over-HTTPS (DoH) in version 86, but the prepopulated DoH providers list/configuration pane was removed after users began reporting performance issues.
 
“Due to a performance issue recently discovered with DNS-over-HTTPS, we have temporarily turned off the built-in list of providers and the auto-upgrade logic that looks at your OS’s DNS setting. Manually providing a resolver URL is still supported,” Microsoft Edge engineer Alex Rowell explained in an Edge Insider forum post.
 
Microsoft has begun testing a fix for the DNS-over-HTTPS (DoH) performance issues, and you now access the built-in list of providers once again in the latest Microsoft Edge Canary and Dev builds.
