I Harry Potter och trollkarlens sten står det:
"No problems, were there?" [Dumbledore asked]
"No, sir - house was almost destroyed, but I got him out all right before the Muggles started swarmin' around. He fell asleep as we was flyin' over Bristol." [Hagrid said]
Dumbledore and Professor McGonagall bent forward over the bundle of blankets. Inside, just visible, was a baby boy, fast asleep. Under a tuft of jet-black hair over his forehead they could see a curiously shaped cut, like a bolt of lightning.

Hur gick Dumbledore - som jag gissar, skickade Hagrid för att undersöka scenen på Potters hem i Godrics Hollow - vet att Potters hade dödats? Varken Dumbledore eller Hagrid var Potters Secret Secretare för Fidelius Charm. Hur var Dumbledore medveten omedelbart att James och Lily hade blivit dödade för att kunna skicka Hagrid snabbt till platsen så att han kunde rädda älskling Harry innan Muggles varnade för situationen (som, för att vara ärlig, verkar lite osannolikt om det fanns någon form av explosion, som det verkar att det sågs när huset var "nästan förstört"). Heck, om huset i närheten av mig plötsligt blåste upp, skulle det ta mig mindre än 10 sekunder att komma ut på min veranda för att se en titt!
Hur kan dessa händelser logistiskt vara meningsfullt?
ETA: Information om Fidelius Charm.
When a Secret-Keeper dies, their secret dies with them, or, to put it another way, the status of their secret will remain as it was at the moment of their death. Everybody in whom they confided will continue to know the hidden information, but nobody else.
Just in case you have forgotten exactly how the Fidelius Charm works, it is
"an immensely complex spell involving the magical concealment of a secret inside a single, living soul. The information is hidden inside the chosen person, or Secret-Keeper, and is henceforth impossible to find - unless, of course, the Secret-Keeper chooses to divulge it" (Harry Potter and the Prisoner of Azkaban)
In other words, a secret (eg, the location of a family in hiding, like the Potters) is enchanted so that it is protected by a single Keeper (in our example, Peter Pettigrew, a.k.a. Wormtail). Thenceforth nobody else – not even the subjects of the secret themselves – can divulge the secret. Even if one of the Potters had been captured, force fed Veritaserum or placed under the Imperius Curse, they would not have been able to give away the whereabouts of the other two. The only people who ever knew their precise location were those whom Wormtail had told directly, but none of them would have been able to pass on the information.

Jag noterar att det inte finns några tecken på att Peter Pettigrew berättade för någon av Potters vistelseort förutom Voldemort, och Voldemort, efter konfrontationen, var inte precis i stånd att spela Tellyfone med Dumbledore!
