Thanks for your reply. Yes I have already communicated with DO team regarding this issue, they have said that they support maximum 200 concurrent downloads for Spaces. They have suggested me to either increase the number of spaces instances or implement CDN or both. Increasing spaces instance can be a bit tricky because our contents are uploaded dynamically from one of our own web consoles. So we can dynamically choose to upload files on difference Spaces instances in round robin fashion. But the problem is not all our videos have equal demand and some videos are viewed more frequently than others, but there’s no way to accurately predict which videos are gonna be high in demand. One solution is to upload same video file to all instances and keep the links in a DB field. Then we can let the frontend website/app to randomly play them out. This way the loads will be distributed properly. That’s a lot of task but doable. Let me know if you have any better ideas.

Currently we are serving everything from Amazon cloudfront CDN which is linked to my DO droplet. This is rather costly. That’s why we are thinking to move to a cheaper yet reliable service.
