DNS for geoip and multi-CDN
One key feature of CDNs, either DIY or well known, is that they use DNS to route users to the closest caching server based on the IP-based geo-location. Ideally, we'd have a trusted DNS provider to run this setup for F-Droid. @CiaranG is already running the DNS on his servers, he might be willing and able to set up geoip there. Otherwise, we already can get VMs and Anycast IP from eclips.is, so someone could set up our own DNS servers with full geoip support.
This is a hard requirement for a multi-CDN setup as discussed in #230 (closed) #229
