Exercise links are down, here's how to solve it

As you may have noticed, the links to the exercises are all dead. 
I'm trying to reach our IT department. In the meantime, you can access the exercises like this: 
1. Click the exercise link, and get to the error page. 
2. Replace "http://www1." with "ftp://ftp.". 
For example, the link to the VIC exercise is: ftp://ftp.idc.ac.il/coursesftp/cs/intro1/Exercises/VIC/Exercise%205.html 
The link to the Gremlins exercise is: ftp://ftp.idc.ac.il/coursesftp/cs/intro1/Exercises/Ex06_gremlins/Ex06.html 
Boaz.
