One possible issue is if servers depend on checking in with other servers to start up correctly. There's going to be some interesting circular dependencies that no one's thought about or hopes will never happen.
Plus if you kept the whole internet off for a year, every server would have expired SSL certificates and might not be able to download new ones without manual intervention.
(there's an analogous problem with the power grid called a black start )
