Having same issue; I'd be worried if I didn't have those backups regularly submitted.
My android wallet is entirely separate from my normal one; I don't have backups of that... Here's hoping their system isn't totally borked, or I may have to go do surgery on my Android to recover a cached copy of the wallet if possible to avoid a 10 BTC loss...
I'm sure they'll be back soon? Would be nice to get some form of acknowledgement on their Twitter or on here, but maybe I'm not looking in the right places.
