It took about 20 minutes instead of 5 but I tested the server that needed rebooting and it's working now.
It's about 9:15PM Pacific time and I cannot access the site at all, only the community pages.
Oh yeah, it's a few minutes past midnight, central time, and every time I try to post or schedule a saved listing I get the home page after a few minutes. I hope it is resolved soon. Auctiva is great when it is working.
