Technical Snags Delay Candidate Development

Earlier this week, the Office of Personnel Management put out this somewhat curious announcement:

Because of technical difficulties, the deadline for the application process to the Federal Candidate Development Program has been extended to midnight Friday, January 25, 2008, or until the end of the day when 500 Fed CDP applications have been received, whichever comes first.

Now, OPM says it won't provide any information to Government Executive on exactly what those "technical difficulties" were. Anybody have any intelligence on that?
