Early this morning (Fri. March 13, 2009) we moved this site to newer, much faster hardware. Changes to surveys, including responses, made between 10 pm last night and 7:45 am today were not carried over to the new site. If you suspect you are missing data, please let us know.
The new server is actually a virtual one, running on a recently purchased real server running VMWare. The virtual servers are created and administered by Academic Computing.
