You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 3.231.0.0/16 has been blocked by ‪ST47‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider. To prevent abuse, web hosts may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a web host's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and they should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 06:15, 30 September 2026. Your current IP address is 3.231.93.245.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

'''SITA''' is a [[multinational corporation|multinational]] [[information technology]] company providing [[IT]] and [[telecommunication service]]s to the air transport industry. The company provides its services to around 400 members and 2,500 customers worldwide, which it claims is about 90% of the world's airline business.<ref name="Customers">((cite web | url=http://www.sita.aero/content/aviation-it-specialist-sita-expands-presence-letterkenny-0 | title=Customers | publisher=SITA AERO | access-date=2015-01-16 | archive-url=https://web.archive.org/web/20130606060442/http://www.sita.aero/content/aviation-it-specialist-sita-expands-presence-letterkenny-0 | archive-date=2013-06-06 | url-status=live ))</ref> Around the world, nearly every passenger flight relies on SITA technology.

==History==
SITA or ''Société Internationale de Télécommunications Aéronautiques'', was founded in February 1949 by eleven [[airline]]s in order to bring about shared infrastructure cost efficiency by combining their [[airline teletype technology|communications]] networks. The eleven original airlines were: [[British European Airways Corporation]] (BEAC), [[British Overseas Airways Corporation]] (BOAC), [[British South American Airways]] (BSAA), [[KLM]], [[Sabena]], [[Swissair]], [[TWA]], Swedish A.G.Aerotransport, [[Danish Air Lines]], [[Norwegian Air Lines]] and [[Air France]]. 

=== World-wide computer network ===
SITA opened its first telecommunications centre in Rome in 1949. Information was manually transmitted using perforated tape and teleprinters. This was the 'first generation' of the network. The 'second generation' SITA High-Level Network (HLN) became operational in 1969, handling data traffic in real time via a [[Message switching|message-switched network]] over [[common carrier]] [[leased line]]s.<ref>((cite conference |last=Chretien |first=G.J. |author2=Konig, W.M. |author3=Rech, J.H. |date=1973 |title=The SITA Network |url=http://rogerdmoore.ca/PS/SITAB.html |location=Sussex, United Kingdom |publisher=Noordhoff International Publishing |pages=373–396 |archive-url=https://web.archive.org/web/20131020140241/http://rogerdmoore.ca/PS/SITAB.html |archive-date=2013-10-20 |book-title=Proceedings of the NATO Advanced Study Institute on Computer Communication Networks |url-status=dead))</ref><ref name="Roberts19782">((cite web |last1=Roberts |first1=Dr. Lawrence G. |date=November 1978 |title=The Evolution of Packet Switching |url=http://www.packet.cc/files/ev-packet-sw.html |url-status=dead |archive-url=https://web.archive.org/web/20160324033133/http://www.packet.cc/files/ev-packet-sw.html |archive-date=24 March 2016 |access-date=5 September 2017 |quote=Almost immediately after the 1965 meeting, Donald Davies conceived of the details of a store-and-forward packet switching system))</ref> It was organised to act like a [[Packet switching|packet-switching]] network.<ref name="Roberts1978">((cite web |last1=Roberts |first1=Dr. Lawrence G. |date=November 1978 |title=The Evolution of Packet Switching |url=http://www.packet.cc/files/ev-packet-sw.html |url-status=dead |archive-url=https://web.archive.org/web/20160324033133/http://www.packet.cc/files/ev-packet-sw.html |archive-date=24 March 2016 |access-date=5 September 2017 |quote=Almost immediately after the 1965 meeting, Donald Davies conceived of the details of a store-and-forward packet switching system))</ref> The 'third generation' Data Transport Network adopted [[X.25]] in 1981, providing global coverage and becoming the world's "largest" [[public data network]].<ref name="history">((cite web|title=SITA History|url=http://www.sita.aero/about-sita/what-we-do/sita-history|work=About SITA > What we do|publisher=SITA|accessdate=16 August 2012|archive-url=https://web.archive.org/web/20120819091302/http://www.sita.aero/about-sita/what-we-do/sita-history|archive-date=19 August 2012|url-status=live))</ref><ref name=":11">((Cite journal |last=Rybczynski |first=Tony |date=2009 |title=Commercialization of packet switching (1975–1985): A Canadian perspective [History of Communications] |journal=IEEE Communications Magazine |volume=47 |issue=12 |pages=26–31 |doi=10.1109/MCOM.2009.5350364 |s2cid=23243636))</ref>
