Swoogle is off line for a day or two. We discovered that our Swoogle server (pear) was compromised. (Yet another PHP-Nuke vulnerability.) We have a plan to bring it back up in a more secure configuration with the database behind a firewall and only the web interface exposed to the elements. A consequence is that only the official URL, HTTP://SWOOGLE.UMBC.EDU/, will work. It’s a jungle out there.
