I just noticed that the server where the databases page resides is
refusing requests. I have put a copy on a different server; I will
keep the two in sync, so you should always be able to find *one* which
works. Sorry about any inconveniences this may have caused.
Here's the URL for the new one:
http://www.pitt.edu/~ethan/pps-database-links.html
(it's just the same as the URL for the old one but no "cs" in the IPname.)
