Problem With Faa Shop On Website

Hi all - wondering if anyone else has experienced this? I set up a subdomain to go to my FAA store quite some time ago (http://shop.jaiart.com/index.html). It's been working fine with no issues, and now it's going to this link: http://shop.fineartamerica.com/index.html when the link above is clicked on. My website is hosted through Zenfolio, but the subdomain was set up through GoDaddy to go the FAA store. Zenfolio had some issues this morning, and is working fine now, but the store link I just noticed is not working. Is this something which could have been caused by Zenfolio having some issues, or is there a problem on the FAA end of things, or ... ? I'm just at a loss as to how to fix the problem, or if it's something I can fix. Any ideas?
