For reference, here are the announcements that were posted during the recovery from the February 19 crash:

While some basic Web service for this course is now back on line, some major components (homework, gradebook, etc.) are not ready to go yet. Check this space later for updates.

Homework, gradebook, etc. are again available.

Due to the character of the failure, work on assigned exercises done in the few days preceding the crash cannot be recovered. As a result, the following will be done "soon" -- within a day or two after the system is again fully operational: all students will receive (in the gradebook) full credit for Homework 5.

All students now have full credit (10 points) in the gradebook for Homework 5.
