Random Online / Offline Status

Our South African reflector XLX655 has been operational now for a couple of months already. It is connected to a high speed enterprise network, proper DELL PowerEdge server, UPS, standby generator etc. The dashboard is always online when you connect to it 24/7. But what I have picked up is the status in the "Reflectorlist" of other dashboards shows XLX655 as red sometimes for a day or two and then goes green again. This red / green behavior seems to be totally random. The reflector seems to function properly, always interlinked to BrandMeister, always trans-coding between DMR and D-Star, nothing strange pickup yet.

Is it perhaps a connection between SA and the world, or is there something in the configuration I need to look at?

Thanks
