Depends. It could be many things. One thing is that due to budget constraints, Universities sometimes don't upgrade their servers when they really need to. For instance, in our case, most of our student facing servers (ftp, user areas, email and web servers) are fairly up to date. However, some of the servers for our internal stuff are way out of date. For instance, the database server used to enable web access to student details is a P90!
Also, Unis don't necessarily have fast enough links (again, due to budget). Where I work, we are lucky. The Campus was only opened in 1999, so our networking hardware is (relatively) new. The main Computing department (who manage the network for the whole University) is also based here, so the link tends to get upgraded frequently, and is well maintained.
