Hetzner is "unlimited fair use" for 1Gbps dedicated servers, which means their average cost is low enough to not be worth metering, but if you saturate your 1Gbps for a month they will force you to move to metered. Also 10Gbps is always metered. Metered traffic is about $1.50 per TB outbound - 60 times cheaper than AWS - and completely free within one of their networks, including between different European DCs.

In general it seems like Europe has the most internet of anywhere - other places generally pay to connect to Europe, Europe doesn't pay to connect to them.
