Ah, just got this notice from Cafe Press:
Dear Shopkeeper,
Over this past weekend we experienced a redundant system failure that resulted in the corruption of a number of images, deeming many unprintable. Essentially, this means that an image server and its backup both failed, and Shopkeeper images were potentially damaged.
Unfortunately, one or more of your images are affected. We are currently working to restore images, and in the meantime you’ll notice that some of your designs show as pended* in your media basket, and are not salable within your stores or in the Marketplace.
Over the next few days we will be removing the pending* status from images as they’re fixed. Our goal is to restore as many as possible, and we anticipate knowing the full results of our work later in the week. We will send a follow-up email to report our status at that time.
We apologize for the inconvenience, and thank you for your patience.
Sincerely,
CafePress
* Pended Images: Generally images are pended as a result of content usage violations. The images pended as a result of this work will be highlighted in red within your Media Basket in your account information, and will appear no different from those pended for content usage reasons. Please note that images pended for content usage reasons will not be removed from pending status as a result of this process.
I see my timing is up to its usual Murphy's Law standards.
