Hi Katmaan,
Yes, the Auctiva website is fully operational once again. If you had any listings that failed to post last night because they were scheduled during the down time we experienced, you should be able to post them successfully at this time by trying again.
If you have any additional questions or concerns, please feel free to contact our customer support team by completing the web form on the following page of our site: http://www.auctiva.com/help/requesthelp.aspx
