Lightning Terminal - node health check status

Does anyone know what this icon represents in Lightning Terminal?

It has suddenly appeared against 4 of the 6 health checks on my node:

Until very recently, all six were appearing as green ticks. I had a peer close a 2m channel and this seems to have impacted the health of my node according to Lightning Terminal. At the same time, the overall node status has changed from “Good” to “Pending”.
