Information about Jabber servers in a convenient table

Today my friend shared an interesting link with me.
On this site, you can see if icq transport is currently available, choose irc, msn, yahoo, aim transport, see what uptime the server has and choose the most reliable one, and also find out how long the server is off, and there are many more useful goodies)
I understand, it does not pull on the article, it is rather a useful link for novice users of Jabber. So I will be glad if this note will help someone in the transition to jabber :)
