Dave,

The problem is that the upstream site Rutgers is sending in stats, but the
name it given is adsl-207-44-114-42.dejazzd.com instead of twister.  If
you want to change the host name in your bin/ldmadmin file to the new name
your stats will start to appear again. The hostname change in the ldmadmin
file should not affect anything else.
