I have a home network set up with a gigabit switch that connects three computers (my desktops) and one laptop all using hardwired connections. Two Synology boxes are plugged into this same switch. The whole setup is connected to my modem/router through a MOCA adapter. Right when I was working on the laptop, moving big files between two Synolys via File Explorer on my other desktop, I got internet cuts on the laptop (the Windows Ethernet icon didn't change even though things were happening). However, the file transfer on the Synology boxes seemed to keep going from my Desktop side. Does this mean only my internet was down and not affecting my LAN or the files moving between the boxes? I'm scared that if the transfer stops suddenly, it might ruin all the data.

I would suggest using your NAS units directly instead of going through your PC. This way you don't create extra traffic from NAS1 all the way to NAS2. You can log in to NAS1 and start transferring files right there to NAS2 without touching your computer. Your PC is just a small window to watch things happen, not part of the transfer itself. A switch handles ports separately; for example, if your laptop is on port 4 and your router is on port 5, then the data moving between ports 1, 2, or 3 never affects ports 4 or 5. Could a long file transfer make the switch too hot? Yes, that could happen but it's very unlikely. Ethernet switches are built to stay stable and cool down easily.

Thanks! On the file transfer part of the window that shows up in my Windows desktop, is there any way I could check if I had just lost the internet connection for a little while?

I might be using a tool to manage things, and you'd see an internet connection tab. But it shows no activity at all for a while.

Also about temporary disconnects: You might see some related error code, warning, or even an informational message getting caught by Reliability History and/or the Event Viewer. Reliability History is easy to use and shows a timeline that helps spot patterns. The Event Viewer needs more time and effort though. To help with Event Viewer:
