Hi,
Auctiva reported they were doing an extended site maintenance period starting late yesterday evening.
As far as I can tell from checking my own account and one other, no problems. However, I would file Support Cases for problems...as that gets the quickest attention.
I have hope that the extensive changes this week are in preparation (at least in part) for Beta 2 of the new eComm Stores, which Jeff suggested would be open to all.
