The s5.myradiostream.com shows that it is up because the website works and it can be pinged ( I actually wrote a little php script to do pretty much what I think your "monitor" does) but the server isn't really working.
It would seem its a problem with the advertising giving authorization. The SHOUTcast D.N.A.S. Status can be accessed and says that the shoutcast server is running and even gives the song that is playing.
You can't connect to the stream link (http://s5.myradiostream.com/xxxxx.htm gives you a not found error) and if you created your own page, which I did, you get an error stating: "The requested URL /stream/xxxx/ads.htm was not found on this server." Because of this the player on the page does not play ... I'm sure its getting a non authorized error.
I believe some work still needs to be done or maybe I have another issue.... I'm not fully sure.
If this is only my server and you need the numbers that fill in the xxx's , let me know
