Price for traffic between datacenters

Hi @andreykoltsov,

There shouldn’t be any additional traffic if you are using LON1 or FRA1. The additional traffic your use is in terms of bandwidth.

Droplets include free outbound data transfer, starting at 1,000 GiB/month for the smallest plan. Excess data transfer is billed at $0.01/GiB. For example, the cost of 1,000 GiB of overage is $10. Inbound bandwidth to Droplets is always free.

Any data transfer sent by a Droplet using a public network interface will count against the transfer pool for that Droplet’s account. All IPv6 traffic uses the public interface. Data transfer between Droplets over the VPC network uses a private network interface.

Transfer allowance is pooled cumulatively at the account level, not individually at the Droplet level. For example, if you run two Droplets for a full month, each with 1,000 GiB/month allowance, you accrue a 2,000 GiB allowance. Let’s say you transfer 1,500 GiB of data with the first Droplet, which is over its individual limit, and 100 GiB of data with the second Droplet, you would still be under the total limit of 2000 GiB by 400 GiB and would not be charged any overage fees.

Accrued transfer does not roll over between months and cannot be transferred between accounts or teams:

Having said that, for account and billing-related questions it’s always best to contact DigitalOcean’s support:
