You could run a
Search for "Connection timed out" or "University" to see other threads. Expand to 'All Forums' and 'All Posts' for best results.
However, the most likely explanation is that they
are blocking ports - they may not necessarily inform you of it because they see no need etc. Many schools, universities, colleges and work places do prevent IRC access due to the possibility of getting viruses or illegal file trading that they don't want on the network.
Really, the only solution is to talk to a network administrator (perhaps the Head of the IT Dept?) and see if they can help you out.
If it does aspire that they have blocked the ports we do not help with evading these blocks.
Best of luck though
