[Iron Man 3] How was J.A.R.V.I.S tired?

Perhaps I misread the scene, but after Stark crash lands in the frozen woods, Jarvis says, "I really think I should sleep now, sir," and then shuts down. 

Now I understand the *suit* losing power... But surely Jarvis is software running from some sort of server hub through a cloud, and not local to the suits? We see proof of that later with the House Party Protocol... Right? 

So was Jarvis just being cute when he said he needed to sleep, or am I missing something?

He was thousands of miles from the central server, and something as complex as Jarvis couldn't possibly operate at full speed and efficiency over 3G. That had to be a local forked copy. Probably all the suits contain a self-stored unit that meshes with the main when in range, but can operate independently. Also protects against Jarvis being corrupted or compromised.
