Route 53 - Geographic Routing to Digital Ocean

Does anyone have experience with AWS Route 53 routing traffic to non-aws resources?

I’m trying to deploy a latency routing node network with Route 53. Only, I’m routing traffic to VPSs hosted on Digital Ocean (they are cheaper).

I can telnet to endpoints on 35997 through route 53 but they seem to block curl requests. Wonder if anyone else has encountered this issue.
