This morning I got a time out trying to go to 
ftp://st.cs.uiuc.edu/pub/Smalltalk/Squeak/, the address given by 
http://minnow.cc.gatech.edu/squeak/1582.  I tried later with same 
result.  Just now, I finally succeeded.

However, trying to update a 3.1ish image, I get the error no new updates on 
squeak.cs.uiuc.edu/Squeak2.0/.  I don't know why it's looking at 2.0, and I 
know there were some changes to the updates servers, but .....

is anything wrong with the server?
