I can't seem to find much on it now as the Delaware AG's office now shows the current reciprocity agreement with Va. I imagine that a google cache search would show it being there one day and when it was removed.
We referenced it on our website's blog back in October. Somewhere between October 14 and January 5, it was observed the reciprocity with Virginia was removed from the AG site. It was obviously more than 3 days, but it was a very short time. It kind of just showed up one day and was gone the next time that you looked for it, hence the "3 day" comment.
