To me that sounds like the school is (perhaps wisely) blocking ports  
they think are unnecessary for security reasons in a school full of  
Windows based machines. Are any of your own machines showing stable  
connection to jabber.sl.org while on their network?

If it is port blocking at the school, there are some tricks that allow  
you to redirect arbitrary traffic over an open port (likely port 80  
for http if the school is allowing direct internet access), but you'd  
need to tweak each Soas install and the remote server running jabber.  
And there's still the chance that the school filtering might be more  
advanced and be introspecting and filtering packets at a lower level  
than just port numbers.
