Some domain auctions are continuously run. These are generally offer / counter offer domain auctions. Since the maximum length of any auction can be 3 months maximum (i.e. 90 days), when the auction expires they are reset to 89 days. Due to a lag in the time between the auction being reset and our servers being updated with the information, you may see an auction that is to expire within a few hours - but the auction has actually been reset to a new three month cycle.
