>Data Transfer from AWS Regions to the Internet is now free for up to 100 GB of data per month (up from 1 GB per region).

Is it 100 GB per region or 100 GB across regions? Because it sounds like the latter.

I read it as total. But that's still a good sized increase. Especially if most of your traffic comes out of 1 or 2 regions.
