Last time I looked from the network graph, more than 99% of the nodes were connected together. I at some point thought that finding those 'islands' was a good idea, to get lots of traffic by being the bridge between them, so I built a tool to check that The few that are not connected keep it that way for a reason.
What tool did you build?

Sorry i did not see the reply. This was in the early code for my lightning node channel advisor (www.lnshortcut.ovh). But as i found out there was actually no 'island', i just abandonned that code.
