Steps to Reproduce:

1. Clone a repository which is only available locally, such as in a company network.
2. Fetch when not connected to the company network.

Observed:
"Last Fetched" will be updated to current date, however in the GitLens debug output the following can be seen:

[4a7d] GitService.fetchAll — e=myrepo, t={"all":false,"prune":false}
[4a7e] Repository(/media/work/source/myrepo/).fetch — {"all":false,"prune":false}
[4a7f] GitService.fetch — e=/media/work/Source/myrepo, t={"all":false,"prune":false}
[4a7d] GitService.fetchAll completed • 50 ms
[4a7a] GitCommandsCommand.execute completed
[/media/work/Source/myrepo] Git Command failed: /usr/bin/git -c core.quotepath=false -c color.ui=false fetch • ssh: Could not resolve hostname gitlab.<company>.com: Name or service not known • Could not read from remote repository. •  • Please make sure you have the correct access rights • and the repository exists. • 161 ms
[/media/work/Source/myrepo] git fetch • 161 ms 
[4a7f] GitService.fetch completed • 167 ms
[4a7e] Repository(/media/work/source/myrepo/).fetch completed • 171 ms

Expected:
"Last Fetched" status message shows "Last Fetched failed" or is not updated to current time

This has been resolved in the latest insiders edition (should be coming to stable soon).

You can install the insiders edition from here. Be sure to disable/uninstall the stable version of GitLens first.
