yahoo delays?

[Vivek Khera <khera @ kcilink . com>]

 From time to time, I expect major delays from hotmail.  Until recently, 
we've had great luck with yahoo delivery.  The last couple of weeks, we 
have seen a tremendous slowdown in deliveries to yahoo, causing some 
serious backlogs in our mail queues.

Has anyone else been experiencing slow email delivery to yahoo?
