That's what I'm trying to understand too. It's this a meteor,tree,etc? Or a human made object,and if so accidental or intentional one. Further risk assessment would be dependent on root cause.
The earliest phrasing I saw internally was "Root cause is identified as a drone attack to DXB61 site". That's somewhat open to interpretation, and could also have simply been incorrect. It was scrubbed from the ticket, though, and it now merely vaguely gestures toward a "power event". The ticket I'd expect to have further detail was locked down.
