Lisp Development Environment Non-Functional

At about 11:30 today (Thursday, September 8) our Lisp development environment for the course has become non-functional due to a silly ¡®pilot error¡¯.  We expect it will take at least a few hours to restore everything to normal, so please bear with us!  We will post an update once the problem is resolved.  Our apologies for the inconvenience!
