Hey conman,
We don't have a standard GDPR package like this ready to go. We would need to sign DPAs with our providers in order to sign an DPA with you (at least if I'm reading things correctly).
We built our regions to be pretty self contained. US data stays in the US, the German mail and web servers data stays on those servers, all of the European servers save backups to Germany, and we can make sure your server is located in Germany (or any of the other EU countries we support).
We can pretty easily list out our sub-processors, security, deletion of data and where data could cross borders if that's sufficient. If it needs to be a formal agreement it would take a lot more work. Especially if we need to have the same agreements and SCCs with our upstream providers.
Feel free to send us a support ticket so we can dig in further!
