Type of site
archive.today (formerly archive.is) is an archive site which stores snapshots of web pages.It retrieves one page at a time similar to WebCite, smaller than 50MB each, but with support for modern ("Web 2.0") sites such as Google Maps and Twitter.
In web archiving, an archive site is a website that stores information on webpages from the past for anyone to view.
WebCite is an on-demand archive site, designed to digitally preserve scientific and educationally important material on the web by making snapshots of Internet contents as they existed at the time when a blogger, or a scholar or a Wikipedia editor cited or quoted from it. The preservation service enables 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.
Web 2.0 refers to websites that emphasize user-generated content, ease of use, participatory culture and interoperability for end users.
Archive.today uses headless browsing to record what embedded resources need to be captured to provide a high-quality memento, and creates a PNG image to provide a static and non-interactive visualization of the representation.
Memento is a United States National Digital Information Infrastructure and Preservation Program (NDIIPP)–funded project aimed at making Web-archived content more readily discoverable.
Portable Network Graphics is a raster-graphics file-format that supports lossless data compression. PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF).
Archive.today can capture individual pages in response to explicit user requests.
Since July 2013, archive.today supports the Memento Project application programming interface (API).
An application programming interface (API) is an interface or communication protocol between a client and a server intended to simplify the building of client-side software. It has been described as a “contract” between the client and the server, such that if the client makes a request in a specific format, it will always get a response in a specific format or initiate a defined action.
Archive.today was founded in 2012. The site originally branded itself as archive.today, but in May 2015, changed the primary mirror to archive.is.In January 2019, it began to deprecate the archive.is domain in favor of the archive.today mirror.
In March 2019, the site was blocked by several Australian internet providers in the aftermath of the Christchurch mosque shootings in an attempt to limit distribution of the footage of the attack.
Australia, officially the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. It is the largest country in Oceania and the world's sixth-largest country by total area. The neighbouring countries are Papua New Guinea, Indonesia, and East Timor to the north; the Solomon Islands and Vanuatu to the north-east; and New Zealand to the south-east. The population of 26 million is highly urbanised and heavily concentrated on the eastern seaboard. Australia's capital is Canberra, and its largest city is Sydney. The country's other major metropolitan areas are Melbourne, Brisbane, Perth, and Adelaide.
The Christchurch mosque shootings were two consecutive terrorist shooting attacks at mosques in Christchurch, New Zealand, during Friday Prayer on 15 March 2019. The attacks began at the Al Noor Mosque in the suburb of Riccarton at 1:40 p.m. and continued at the Linwood Islamic Centre at about 1:55 p.m. The gunman live-streamed the first attack on Facebook Live.
According to GreatFire.org, archive.today has been blocked in China since March 2016,archive.li since September 2017, and archive.fo since July 2018.
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.
In Russia, only HTTP access is possible; HTTPS connections are blocked.
Archive.today currently blocks requests from Cloudflare's recursive DNS resolver, 22.214.171.124.
Additionally, since late 2018, Archive.today has implemented a data cap limitation, presumably to help protect against denial-of-service attacks. Individual users can only archive and/or retrieve approximately 10 to 20 megabytes of data per day. After that limitation is reached, their web server blocks the individual user's IP address by no longer responding.[ citation needed ]
Archive.today records only text and images, excluding video, xml, rtf, spreadsheet (xls or ods) and other non-static content. It keeps track of the history of snapshots saved, returning to the user a request for confirmation before adding a new snapshot of an already saved Internet address.
Web pages cannot be duplicated from archive.is to web.archive.org as second-level backup, as archive.is places a exclusion for Wayback Machine and don't save its snapshots in WARC format. The reverse - from web.archive.org to archive.is - is possible, 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 Archive.today does not use this.
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.
Once a web page is archived, it cannot be deleted directly by any Internet user. [ citation needed ]Nevertheless, archive.today regularly controls or deletes web pages saved some days before, without any policy or right of discussion and appeal.
While saving a dynamic list, archive.today searchbox shows only a result that links the previous and the following section of the list (e.g. 20 links for page).The other web pages saved are filtered, and sometimes may be found by one of their occurrences.
The search feature is backed by Google CustomSearch. If it delivers no results, archive.is attempts to utilize Yandex Search.
If a page has already been archived, archive.is asks the user to confirm archiving a new revision, instead of immediately archiving it.
Content-control software, commonly referred to as an Internet filter, is software that restricts or controls the content an Internet user is capable to access, especially when utilised to restrict material delivered over the Internet via the Web, e-mail, or other means. Content-control software determines what content will be available or be blocked.
The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web, where hypertext documents include hyperlinks to other resources that the user can easily access, for example by a mouse click or by tapping the screen in a web browser.
The World Wide Web (WWW), commonly known as the Web, is an information system where documents and other web resources are identified by Uniform Resource Locators, which may be interlinked by hypertext, and are accessible over the Internet. The resources of the WWW may be accessed by users by a software application called a web browser.

Link rot is the process by which hyperlinks on individual websites or the Internet in general tend to point to web pages, servers or other resources that have become permanently unavailable. There is no reliable data on how long web pages and other resources survive: the estimates vary dramatically between different studies, as well as between different sets of links on which these studies are based.
Ad blocking or ad filtering is a software capability for removing or altering online advertising in a web browser or an application. The most popular ad blocking tools are browser extensions. Other methods are also available.

An HTTP cookie is a small piece of data sent from a website and stored on the user's computer by the user's web browser while the user is browsing. Cookies were designed to be a reliable mechanism for websites to remember stateful information or to record the user's browsing activity. They can also be used to remember arbitrary pieces of information that the user previously entered into form fields such as names, addresses, passwords, and credit card numbers.
Internet censorship is the control or suppression of what can be accessed, published, or viewed on the Internet enacted by regulators, or on their own initiative. Individuals and organizations may engage in self-censorship for moral, religious, or business reasons, to conform to societal norms, due to intimidation, or out of fear of legal or other consequences.
