Seems the servers melted down last night. We've made our web service provider aware of the issue and they are looking into it. Meanwhile, please don't fish, and please spread word to anybody asking what happened to 7Seas. We will update this forum thread when we get news about the situation or when the issue is resolved. Thanks for your patience.
UPDATE 10:45am: The issue seems to be resolved -- I can't log into SL right now, but I see item requests being processed including vendor buys, so I'm guessing we're All Clear. As always, if you have any delivery issues please contact 7Seas Sass for assistance. If your vendor says "Vendor Offline" then wait an hour and it should restore itself.
