Overview.
[The way the IDE works]("How the IDE works" article), when a student saves changes to a file in the IDE, those changes are uploaded to the Learn IDE Server. This process is known as "Syncing". This can happen for a number of reasons, and can also manifest itself as many different symptoms. The fixes for these different symptoms vary a little bit, but are essentially the same thing: repairing the synchronization between the IDE and the IDE Server.
Lab Folder With Wrong Contents
Sometimes when a lab repo is cloned to the IDE Server (and the to your computer), the contents of the folder on your computer will not match the contents of that same folder on the IDE Server as it should. This can look like an empty folder in the file tree. This can look like having only a few files instead of all the files. In this case, you should be able to right-cick on the lab's folder and choose `ReSync with Learn IDE Server` (screenshot?).

  • How often do you notice it disconnecting? Once a day? Once a week? 3 times an hour?

  • Packet loss summary

    Mac/Linux: Open up terminal and run ping google.com -c 25 and get the response

    Windows: Go to the start menu and search for CMD to open up the command prompt. Have them run ping google.com -n 25 and get the response.

    We only need that last part:

25 packets transmitted, 25 packets received, 0.0% packet loss
