Why do some file types have traffic multipliers?

Different file types can carry different upstream cost, bandwidth, queueing, and retry overhead, so multipliers reflect the real transfer cost.

Are multipliers the same for every provider?

No. Different upstream restrictions and transfer conditions can lead to different multiplier rules.

Different upstream sources do not have the same download cost. The main differences come from:

Because of that, the platform sets multipliers by type to reflect the real transfer cost and keep the service sustainable.
