Enable Byte-Range Requests

Request from Chloé Bringmann:

I ran into an error when trying to upload the RSS feedRSS Feed RSS is an acronym for Real Simple Syndication which is a type of web feed which allows users to access updates to online content in a standardized, computer-readable format. This is the feed. on Apple for the new WP Briefing podcast. Would you be able to assist with this?I submitted the WP Briefing podcast to Apple and got the following error:

Can’t submit your feed. Your episodes are hosted on a server which does not support byte-range requests. Enable byte-range requests.

Is this something we can do on w.org, or would this be something where we want to utilize a CDN to serve the files instead?
