Beirut was founded the night of March the 21st of the year 2005 by Stefano El Douaihy “Stefano”. The founder and his friend Mike Minassian "Hayasdan" of #Beyrouth on the Undernet IRC network, being frustrated with the current lame users on Undernet and wanting an alternate IRC network, they created Beirut IRC network as an alternative.

Starting when Mohamad Dimashk "Jimie" of #Liban DALnet joined the team and launched the first joint server which became Verdun. The next day , Dimitar Tnokovski "Mitko" came and became the Services & Routing Administrator.

On April the 7th, Beirut changed its services and servers from beware to srvx, and from IRCu daemon to Nefarious.

The network grew fast in a very short period of time and reached 9 servers in late summer 2005.

On January the 30th, Hani Mouneimne "Sm0oth^" of ChatNet joined the club and made a big contribution by donating Hamra server and free hosting.

Publicly listed on February the 8th of the year 2006 in servers.ini of mIRC, Beirut immediately became a target of drones and spam bots attacks and was about to turn into chaos if "SanitariuM" hadn't joined the staff and scripted Snoop Service which halted the attacks and it has been protecting the network ever since. Beirut survived!

Through its short history, Beirut has been repeatedly damaged by attacks such as floods and DDos. After Israel started war on Lebanon (see Lebanon-Israel war), the attacks weren't only on the Lebanese land, but it was also over the Internet, where Israeli drone runners were attacking with botnets. But, like the mystical Phoenician phoenix, it has risen from its ashes.

On December the 22nd of the year 2006, after weeks of hard coding, "Hal9000" made Beirut proud to be the first Nefarious IRCu network to be running Denora.

On February the 20th, Beirut's red army team smashed all rival IRC networks in the mIRC Tanks tournament.

As of 2007, Beirut network celebrated its 2nd anniversary on the 21st of March.

Joined by the powerful Lebanese Diaspora, Beirut has acquired a reputation as “The chat that never sleeps”.

With an average real-time user count of 400 users and 110 channels in 2007, Beirut has become the main Middle Eastern IRC network and SearchIRC ranked it around the 150th most populous network in the world.

On April the 7th, Beirut changed its services from srvx to X3.

In June 2008, Beirut.com domain got hacked and caused DNS problems . The network went back online in November. The user count is highly reduced due to the 5 months of disruption.

Beirut  has recovered and remains functional. Users growth is largely accomplished through its users and partners who brought the best of them to the network which flourishes every day.
