Datapath.io: Provider-Independent Elastic IP Addresses

But... what happens if datapath.io goes down?

I think the idea is that datapath only functions when you go down. ie: if only you go down, datapath will fix it via BGP magic. If datapath is down and you are up, stuff continues to work.

I assume this is BGP routing as a service (which sounds cool).

But, would this not break the internet if everyone used it? routing individual IPs (rather than large blocks) sounds like it would end in chaos?

This is a clever architecture; I never thought about using VPC direct connect to get out to the Internet.

In general, most ISPs will drop any routes more specific than a /24. Presumably datapath has negotiated with some specific providers to allow /32s; it's up to that ISP to scale their routers to handle it; other ISPs will only see the /24 aggregate.
