Spaces subscriptions include 1,024 GiB of outbound data transfer (from Spaces to the internet), which is shared between all Spaces. Additional outbound transfer is $0.01/GiB. Outbound data transfer is free in the following cases:
From Spaces in NYC3 to Droplets in NYC1, NYC2, and NYC3
From Spaces in SGP1 to Droplets in SGP1
From Spaces in SFO2 to Droplets in SFO1, SFO2, and SFO3
From Spaces in AMS3 to Droplets in AMS2 and AMS3
From Spaces in FRA1 to Droplets in FRA1
Inbound bandwidth to Spaces never counts against your Spaces transfer allowance.
Droplets have their own transfer allowance, independent of Spaces. Traffic from Droplets to Spaces does not count against your Spaces transfer allowance (because inbound bandwidth to Spaces is free), but does currently count against your Droplets’ outbound transfer allowance. We’re working on changing this behavior.
