ALL ON-LINE COMPONENTS ARE BACK TO WORKING NORMALLY.

 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 HomeworkA 5 and HomeworkB 5. All HomeworkA 4 scores (in the gradebook) will be adjusted to include the maximum credit that each student could have earned, given that set 4 was at 90% credit possible during the time when work was lost.
The HomeworkA 5 and HomeworkB 5 and HomeworkA 4 score adjustments described above have now been installed in the gradebook.
Once the gradebook becomes available again, the re-scoring of the "...zero intensity at a receiver at C..." question on the midterm exam (described on the Gradebook menu page) will need to be applied again to scores stored in the gradebook. That also might not happen for a day or two.
The re-scoring of that midterm exam question has been done (again) and the raw and scaled midterm exam scores stored (again) in the gradebook.
