I understand that (assuming a suitable OS) Intune clients will share updates across a LAN using Peer Distribution.

From the technet page:

The first computer to retrieve content from the Windows Intune service becomes a source for that content within the same subnet for other computers requesting the same content. When a second computer requests the same content, it downloads the content metadata from the Windows Intune service. The second computer then sends a request for the segment hashes on the local network to determine if any other client already has the data cached. Finding the first client, the second client retrieves the content locally from it.

My question is - what will happen to a request from the third computer if the first computer is powered off, but computer two is powered on and has the content?

Will the second computer make it available to the third computer, or will the third computer need to download it again, and then become authoritive on the LAN for that content since it has the newest version?

We operate a broad global network with many, many low bandwidth locations where downloading updates can easily saturate an internet connection and make it unusable.  The less times that content has to be downloaded the better!
