Our flight server is operating 24/7 and is getting some good usage now.
The direct link to the server is: http://22.214.171.124:85/
I have that link set up on my desktop so that I can see if the server is on and who is flying on it. The link updates every minute, so I can monitor it for traffic and join in on an impromptu multiplayer session when it's in use.
Hope the link is helpful to you. If you need any help in creating a desktop icon to get to the link, please send me a private message or email me at LJ922@flightsim.com.
