The owner of self-serve web archiving tool Archive.today has expressed concern over Cloudflare 1.1.1.1 not passing the contents of this field on to the authoritative DNS server for Archive.today, and has in response configured the site's authoritative DNS servers to consider Cloudflare DNS requests invalid—effectively blocking 1.1.1.1 from resolving the website DNS records.
DNS over HTTPS (DoH) is a protocol for performing remote Domain Name System (DNS) resolution via the HTTPS protocol. A goal of the method is to increase user privacy and security by preventing eavesdropping and manipulation of DNS data by man-in-the-middle attacks [1] by using the HTTPS protocol to encrypt the data between the DoH client and the DoH-based DNS resolver.

Cloudflare timed out contacting the origin server. 523 Origin Is Unreachable Cloudflare could not reach the origin server; for example, if the DNS records for the origin server are incorrect or missing. 524 A Timeout Occurred Cloudflare was able to complete a TCP connection to the origin server, but did not receive a timely HTTP response.
A public recursive name server (also called public DNS resolver) is a name server service that networked computers may use to query the Domain Name System (DNS), the decentralized Internet naming system, in place of (or in addition to) name servers operated by the local Internet service provider (ISP) to which the devices are connected.

1.1.1.1 is a recursive DNS resolver. Cloudflare runs an authoritative DNS resolver with a network of over 20 million Internet properties. With the recursor and the resolver on the same network, some DNS queries can be answered directly. [third-party source needed]
DNS over TLS was first implemented in a public recursive resolver by Quad9 in 2017. [ 24 ] [ 25 ] Other recursive resolver operators such as Google and Cloudflare followed suit in subsequent years, and now it is a broadly-supported feature generally available in most large recursive resolvers.
The average rate for shorter 15-year terms is 6.37% for purchase and 6.36% for refinance, up 10 basis points from 6.27% for purchase and 6 basis points from 6.30% for refinance this time last week ...
[11] Microsoft Windows uses a stub resolver, and Windows Server 2008 R2 and Windows 7 in particular use a non-validating but AD-bit-aware stub resolver. [6] [7] A validating stub resolver can also potentially perform its own signature validation by setting the Checking Disabled (CD) bit in its query messages. [11]
