The Mesh team mentioned a forthcoming Service Update on their blog today. Just though it would be worth letting you Meshers know

We're doing some server maintenance over the next couple days to update some of our configuration information.  During this time you may experience Live Mesh service outages, including Live Mesh folders that are not synchronizing, or an inability to establish Live Mesh Remote Desktop connections to your devices. We'll update here once we've completed this work.  Thanks for your patience as we get everything patched up
