archive.today

archive.today (formerly archive.is) is an archive site which stores snapshots of web pages.[2] It retrieves one page at a time similar to WebCite, smaller than 50 MB each, but with Web 2.0 sites (such as Google Maps and Twitter) included.

Archive.is 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.[3]

Unlike crawlers such as Wayback Machine, archive.today only captures individual pages in response to explicit user requests, and so does not obey the robots exclusion standard.[4] Because of this, website owners cannot unilaterally remove snapshots at will unlike other sites such as Wayback.[5]

Since July 2013, archive.is supports the Memento Project application programming interface (API).[6][7]

History

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.[8] In January 2019, it began to deprecate the archive.is domain in favor of the archive.today mirror.[9]

Worldwide availability

China

According to GreatFire.org, archive.is has been blocked in China since March 2016,[10] archive.li since September 2017,[11] and archive.fo since July 2018.[12]

Finland

On July 21, 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.[13]

Russia

In Russia, only HTTP access is possible; HTTPS connections are blocked.[14][15]

Features

Archive.is records only text and images, excluding video 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.[16]

At November 2018, Archive.is codifies snapshots with an alphanumeric case-sensitive code of five elements. Hence, any element may have one of 42 possible values, between:

1. ten digits, from 0 to 9.
2. 32 letters, 16 of the English alphabet, whose number is doubled by 16 capital letter.

The global amount of possible combinations is given by the conditional probability theorem, as follows: ${\displaystyle 42^{5}=130.691}$  milions of identifiers.

Web pages cannot be duplicated from http://archive.is to http://www.archive.org as second-level backup.[citation needed][why?] The reverse - from www.archive.org to archive.is - is possible,[17] but the copy usually takes more time than a direct capture. Some web sites can't be saved by either Internet Archive or archive.is due to their robots.txt file.

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.[18]

Once a web page is archived, it cannot be deleted directly by any Internet user.[19]

While saving a dynamic list, archive.is searchbox 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.
