Is Yahoo aware of this problem? The Physics category typically?

Is Yahoo aware of this problem? The Physics category typically gets 3 or more questions per hour. However, for the last 2 weeks (at least) the list of open questions has had recent questions less than 2 hours old (normal) but then the next question is 2 weeks old. I visit often enough that I know that there should have been 100's of questions listed from that large jump in time. At times, instead of 2 hours of questions with typical frequency, there are only 2 questions (perhaps received over 1/2 hour period) before it jumps to questions from 2 weeks ago.
