Following up on this thread.

We want codehost connection issues to be much more noticeable for users of Sourcegraph. Two things that can be improved on are:

1. @mrnugget suggested that it would be nice to have a "Test Repository Connection" button on the codehost config page that would let you validate a codehost config by sending an actual request to the codehost without having to save the codehost config first.

2. Make errors reaching the codehost (like the image above) more obvious. After talking with @cbart, one way to do this would be to add a ping to the codehost as part of the repo-syncing process and avoid the repo-sync if the ping fails.

Scope

For now:

• GitHub
• GitLab
• Bitbucket Server
• Frontend side
