We have been working on some major server improvements most of this year, and to cut a long story short we're going to be migrating from our current hosting partner to Firehost, which will ease our continued growth and security/compliance burdens.
We are very (very) excited about this move, but in order to make it happen we will need to take the entire FoxyCart.com system down for a period of time. We anticipate a 2 hour window, but are blocking out 3 hours to be safe.

Please see the status.foxycart.com notice
for complete details (which also will be emailed to every FoxyCart admin user), and post here if you have any questions.
IF YOU'RE USING BLUEFIN or ORBITAL, or have otherwise tied specific functionality to FoxyCart's IP address (which you generally shouldn't be doing), you'll need to update that IP to [coming soon] (emailed to Bluefin users already).
