Gandalf
Gandalf's primary mode of transport remains the horse, specifically Shadowfax, lord of all horses, capable of covering approximately 200 miles per day under optimal conditions. Even accounting for his occasional use of giant eagles, the wizard's information delivery system operates on a timeline measured in days, weeks, or centuries. Indeed, he spent 17 years researching the nature of Bilbo's ring before concluding it required attention. His approach to urgency might charitably be described as 'thoroughly considered'.
The Internet
The Internet transmits data at velocities approaching 299,792 kilometres per second through fibre optic cables, effectively achieving near-instantaneous global communication. A message sent from London to Sydney arrives in approximately 0.17 seconds. This represents a speed advantage over equestrian-based messaging systems of roughly seventeen billion to one. Even Gandalf's eagles, magnificent though they may be, cannot compete with photons travelling through glass threads thinner than human hair.
