Web archiving
Available in Multilingual
LaunchedMay 16, 2012;11 years ago (2012-05-16) [2] (or is a web archiving site, founded in 2012, that saves snapshots on demand, and has support for JavaScript-heavy sites, such as Google Maps, and progressive web apps, such as X. [3] records two snapshots: one replicates the original webpage including any functional live links; the other is a screenshot of the page. [4]


The website does not provide information on the identity of the operator(s). [5]

History was founded in 2012. The site originally branded itself as, but in May 2015, changed the primary mirror to [6]

In January 2019, it began to deprecate the domain in favor of other mirrors. [7]


Functionality can capture individual pages in response to explicit user requests. [8] [9] [10] Since its beginning, it has supported crawling pages with URLs containing the now-deprecated hash-bang fragment (#!). [11] records only text and images, excluding XML, RTF, spreadsheet (xls or ods) and other non-static content. However, videos for certain sites, like Twitter (formerly X), are saved. [12] It keeps track of the history of snapshots saved, requesting confirmation before adding a new snapshot of an already saved page. [13] [14]

Pages are captured at a browser width of 1,024 pixels. CSS is converted to inline CSS, removing responsive web design and selectors such as :hover and :active. Content generated using JavaScript during the crawling process appears in a frozen state. [15] HTML class names are preserved inside the old-class attribute. When text is selected, a JavaScript applet generates a URL fragment seen in the browser's address bar that automatically highlights that portion of the text when visited again.

Web pages cannot be duplicated from to as second-level backup, as places an exclusion for Wayback Machine and does not save its snapshots in WARC format. The reverse—from to—is possible, [16] but the copy usually takes more time than a direct capture. Some web sites get deleted from Internet Archive's listings retroactively or blocked from being saved due to their robots.txt file, but does not use this. [10]

The research toolbar enables advanced keywords operators, using * as the wildcard character. A couple of quotation marks address the search to an exact sequence of keywords present in the title or in the body of the webpage, whereas the insite operator restricts it to a specific Internet domain. [17]

Once a web page is archived, it cannot be deleted directly by any Internet user. [18] Removing advertisements, popups or expanding links from archived pages is possible by asking the owner to do it on his blog. [19]

While saving a dynamic list, search box shows only a result that links the previous and the following section of the list (e.g. 20 links for page). [20] The other web pages saved are filtered, and sometimes may be found by one of their occurrences. [13] [ clarification needed ]

The search feature is backed by Google CustomSearch. If it delivers no results, attempts to utilize Yandex Search. [21]

While saving a page, a list of URLs for individual page elements and their content sizes, HTTP statuses and MIME types is shown. This list can only be viewed during the crawling process.

One can download archived pages as a ZIP file, except pages archived since 29 November 2019, when changed their browser engine from PhantomJS to Chromium. [22]

In July 2013, began supporting the API of the Memento Project. [23] [24]

Worldwide availability

Australia and New Zealand

In March 2019, the site was blocked for six months by several internet providers in Australia and New Zealand in the aftermath of the Christchurch mosque shootings in an attempt to limit distribution of the footage of the attack. [25] [26] It has since been unblocked[ citation needed ].


According to, has been blocked in mainland China since March 2016, [27] since September 2017, [28] since July 2018, [29] as well as since December 2019. [30]


On 21 July 2015, the operators blocked access to the service from all Finnish IP addresses, stating on Twitter that they did this in order to avoid escalating a dispute they allegedly had with the Finnish government. [31]


In 2016, the Russian communications agency Roskomnadzor began blocking access to from Russia. [32] [33]

Cloudflare DNS availability

Since May 2018 [34] [35] Cloudflare's DNS service would not resolve's web addresses, making it inaccessible to users of the Cloudflare DNS service. Both organizations claimed the other was responsible for the issue. Cloudflare staff stated that the problem was on's DNS infrastructure, as its authoritative nameservers return invalid records when Cloudflare's network systems made requests to countered that the issue was due to Cloudflare requests not being compliant with DNS standards, as Cloudflare does not send EDNS Client Subnet information in its DNS requests.

<span class="mw-page-title-main">Denial-of-service attack</span> Type of cyber-attack

In computing, a denial-of-service attack is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to a network. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled. The range of attacks varies widely, spanning from inundating a server with millions of requests to slow its performance, overwhelming a server with a substantial amount of invalid data, to submitting requests with an illegitimate IP address.

<span class="mw-page-title-main">Content delivery network</span> Layer in the internet ecosystem addressing bottlenecks

A content delivery network or content distribution network (CDN) is a geographically distributed network of proxy servers and their data centers. The goal is to provide high availability and performance by distributing the service spatially relative to end users. CDNs came into existence in the late 1990s as a means for alleviating the performance bottlenecks of the Internet as the Internet was starting to become a mission-critical medium for people and enterprises. Since then, CDNs have grown to serve a large portion of the Internet content today, including web objects, downloadable objects, applications, live streaming media, on-demand streaming media, and social media sites.

WebCite is an on-demand archive site, designed to digitally preserve scientific and educationally important material on the web by taking snapshots of Internet contents as they existed at the time when a blogger or a scholar cited or quoted from it. The preservation service enabled verifiability of claims supported by the cited sources even when the original web pages are being revised, removed, or disappear for other reasons, an effect known as link rot.

Server Name Indication (SNI) is an extension to the Transport Layer Security (TLS) computer networking protocol by which a client indicates which hostname it is attempting to connect to at the start of the handshaking process. The extension allows a server to present one of multiple possible certificates on the same IP address and TCP port number and hence allows multiple secure (HTTPS) websites to be served by the same IP address without requiring all those sites to use the same certificate. It is the conceptual equivalent to HTTP/1.1 name-based virtual hosting, but for HTTPS. This also allows a proxy to forward client traffic to the right server during TLS/SSL handshake. The desired hostname is not encrypted in the original SNI extension, so an eavesdropper can see which site is being requested. The SNI extension was specified in 2003 in RFC 3546

8kun, previously called 8chan, Infinitechan or Infinitychan, is an imageboard website composed of user-created message boards. An owner moderates each board, with minimal interaction from site administration. The site has been linked to white supremacism, neo-Nazism, the alt-right, racism and antisemitism, hate crimes, and multiple mass shootings. The site has been known to host child pornography; as a result, it was filtered out from Google Search in 2015. Several of the site's boards played an active role in the Gamergate harassment campaign, encouraging Gamergate affiliates to frequent 8chan after 4chan banned the topic. 8chan is the home of the discredited QAnon conspiracy theory.

<span class="mw-page-title-main">Domain fronting</span> Technique for Internet censorship circumvention

Domain fronting is a technique for Internet censorship circumvention that uses different domain names in different communication layers of an HTTPS connection to discreetly connect to a different target domain than is discernable to third parties monitoring the requests and connections.

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 by using the HTTPS protocol to encrypt the data between the DoH client and the DoH-based DNS resolver. By March 2018, Google and the Mozilla Foundation had started testing versions of DNS over HTTPS. In February 2020, Firefox switched to DNS over HTTPS by default for users in the United States. In May 2020, Chrome switched to DNS over HTTPS by default.

EDNS Client Subnet (ECS) is an option in the Extension Mechanisms for DNS that allows a recursive DNS resolver to specify the subnetwork for the host or client on whose behalf it is making a DNS query. This is generally intended to help speed up the delivery of data from content delivery networks (CDNs), by allowing better use of DNS-based load balancing to select a service address near the client when the client computer is not necessarily near the recursive resolver.

DNS over TLS (DoT) is a network security protocol for encrypting and wrapping Domain Name System (DNS) queries and answers via the Transport Layer Security (TLS) protocol. The goal of the method is to increase user privacy and security by preventing eavesdropping and manipulation of DNS data via man-in-the-middle attacks. The well-known port number for DoT is 853. is a free Domain Name System (DNS) service by the American company Cloudflare in partnership with APNIC. The service functions as a recursive name server, providing domain name resolution for any host on the Internet. The service was announced on April 1, 2018. On November 11, 2018, Cloudflare announced a mobile application of their service for Android and iOS. On September 25, 2019, Cloudflare released WARP, an upgraded version of their original mobile application.
