I stand corrected about our site status. The site isn't actually down...I've been using it all afternoon...but I'm hearing from our technical people that there is a problem where users are getting a "page cannot be found error" in Auctiva Checkout. So...it would look to them like we are down.
This is being actively investigated by our engineering & IT now. If you have buyers with this problem, please contact Auctiva Support if you haven't already done so.
