We have data-centers in Oslo (Norway), Amsterdam (Netherlands) and New York (USA). If your audience is in a small geographical area close to either of these locations then there is no need for CDN. If you however have an international and global audience then our Cloudflare CDN integration with Railgun is the right fit for you.
We do not move data from our European data-centers outside the EU/EFTA, and the backups we keep are also stored within EU/EFTA. This is important for us, and for you, with regards to GDPR compliance.
