Don introduces the Offline Indicator Theme Component, a simple tool that displays a notification when users experience internet connection issues. The component is customizable, allowing administrators to adjust the icon (using FontAwesome), width (desktop only), and border radius. It also supports translations and displays in the bottom right corner on desktop.
During the discussion, Paracelsus asks if the indicator functions during forum rebuilds. JammyDodger initially clarifies that theme components do not require rebuilds to install, but Canapin points out the question was about whether the message appears during the rebuild process. Don confirms that this specific component does not show during rebuilds, as it relies on detecting local connection issues rather than server-side status. He suggests using a global notice for rebuild alerts to avoid confusing users about the source of the problem. Jagster reports a code update warning regarding the component, which Don addresses by linking to a GitHub commit that resolves the issue, thanking @davidkingham for the pull request.
This one will not shown during rebuild. I used to create an offline indicator with offline.js that is always checks favicon, makes requests so that shown during rebuild too. But that seems to unnecessary to this feature for me and also can confuse users where is the problem? Server side or with their internet connection.
I believe you can do this with global notice too. Just add a notice before rebuild.
This theme component is a simple offline indicator which appears when user have internet connection problems.
Yes. That does indeed make much more sense. 
My bad.
