AltaVista was an early web search engine established in 1995. It was once one of the most popular search engines, but it lost ground to Google and was purchased by Yahoo! in 2003, which retained the brand but based all AltaVista searches on its own search engine. On July 8, 2013, the service was shut down by Yahoo! and since then, the domain has redirected to Yahoo!'s own search site.==Origins==AltaVista was created by researchers at Digital Equipment Corporation's Network Systems Laboratory and Western Research Laboratory who were trying to provide services to make finding files on the public network easier. Paul Flaherty came up with the original idea, along with Louis Monier and Michael Burrows, who wrote the crawler and indexer, respectively. The name "AltaVista" was chosen in relation to the surroundings of their company at Palo Alto, California. AltaVista publicly launched as an internet search engine on December 15, 1995 at altavista.digital.com.At launch, the service had two innovations that put it ahead of other search engines available at the time: it used a fast, multi-threaded crawler (Scooter) that could cover many more webpages than were believed to exist at the time, and it had an efficient back-end search, running on advanced hardware.:Email from early January, 1996:Thank you for your comments.

==Origins==
AltaVista was created by researchers at Digital Equipment Corporation's Network Systems Laboratory and Western Research Laboratory who were trying to provide services to make finding files on the public network easier.
Paul Flaherty came up with the original idea,
along with Louis Monier and Michael Burrows, who wrote the crawler and indexer, respectively. The name "AltaVista" was chosen in relation to the surroundings of their company at Palo Alto, California. AltaVista publicly launched as an internet search engine on December 15, 1995 at altavista.digital.com.〔

:Email from early January, 1996:
Thank you for your comments. As we are starting up the Beta phase of
the Alta Vista project, we are trying to respond individually to
some of the messages we have received.
We are putting the following hardware information on the site.
Alta Vista is a very large project, requiring the cooperation of at
least 5 servers, configured for searching huge indices and handling
a huge Internet traffic load. The initial hardware configuration
for Alta Vista is as follows:
Alta Vista -- AlphaStation 250 4/266
4 GB disk
196 MB memory
Primary web server for gotcha.com
Queries directed to WebIndexer or NewsIndexer
NewsServer -- AlphaStation 400 4/233
24 GB of RAID disks
160 MB memory
News spool from which news index is generated
Serves articles (via http) to those without news server
NewsIndexer -- AlphaStation 250 4/266
13 GB disk
196 MB memory
Builds news index using articles from NewsServer
Answers news index queries from Alta Vista
Spider -- DEC 3000 Model 900 (replacement for Model 500)
30 GB of RAID disk
1GB memory
Collects pages from the web for WebIndexer
WebIndexer -- Alpha Server 8400 5/300
210 GB RAID disk (expandable)
4 GB memory (expandable)
4 processors (expandable)
Builds the web index using pages sent by Spider.
Answers web index queries from Alta Vista
Thank you,
Alta Vista Technical Support
