the script itself use a fsockopen command to check the certain port and if it get a response then it give a redirected header to show the image (dead or alive)
then for the iframe , the script just take some mysql data and return that certain value
the exploads for iframe wont harm my server as there is not realy information taken from it
certain cehcks are included in the script ( its php ) to prevent wrong data execution
and my firewall blocks the other attacks that can happens (like port scanning )

Update ( 16/11/2011)
i going script the script a bit differend so you should see the latest sucesfully uptime
on that way you can see how long the server is already down
then i will make it that servers taht are down longer then 1 moth will be removed from the list ( so make sure your server doesnt stay offline for 30 days :P )
then as last i going add a serperated page for the live code , so you can check your server at realtime from your site , but that it is easyer to find and just contains the info you need
