What happens to a deal if the internet cuts?

If a network error occurs (internet cuts), what would our status be at this point ? does Filecoin support a resume functionality? Or should we consider the deal rejected / failed?

If a client loses network connectivity after a deal has been accepted but before data finishes transferring, the deal should be considered failed. If a client loses connectivity after data has been transferred, the miner will proceed with sealing the data and submitting the PoSt.
