test(panel): vis hvad genstart-kaldet gør, når panelet tier eller siger nej
Et 502 i produktion så ud som om kaldet til panelet hang. Det gør det ikke: et panel, der aldrig svarer, giver 202 efter ti sekunder, og et panel, der afviser, giver 502 med sin egen statuskode i teksten. Begge dele står nu som prøver, så næste gang mistanken falder på handleren, kan den frikendes uden at gætte. Hvad der så gav Cloudflares 502 i produktion, er stadig uafklaret.
