Techniques for caching media content when streaming live events

One or more non-transitory computer readable media including instructions that, when executed by one or more processors included in a first edge server included in a plurality of edge servers, cause the one or more processors to cache segments associated with live events by performing the steps of:

• at a first point-in-time, storing a first segment of a first downloadable that is associated with a first live event in a first high priority list;
• at a second point-in-time, determining that the first segment is at a tail of the first high priority list, wherein the second point-in-time is subsequent to the first point-in-time;
• upon determining that the first segment is at the tail of the first high priority list, further determining that an age of the first segment is greater than a cutoff threshold;
• and
• in response to determining, by the first edge server, that the first downloadable is uniquely assigned to a second edge server included in the plurality of edge servers, and determining that the age of the first segment is greater than the cutoff threshold, moving the first segment from the first high priority list to a first low priority list.

A first system included in a plurality of systems, the first system comprising:

• one or more memories storing instructions;
• and
• one or more processors coupled to the one or more memories that, when executing the instructions, perform the steps of:
• at a first point-in-time, storing a first segment of a first downloadable that is associated with a first live event in a first high priority list;
• at a second point-in-time, determining that the first segment is at a tail of the first high priority list, wherein the second point-in-time is subsequent to the first point-in-time;
• upon determining that the first segment is at the tail of the first high priority list, further determining that an age of the first segment is greater than a cutoff threshold;
• and
• in response to determining, by the first system, that the first downloadable is uniquely assigned to a second system included in the plurality of systems, and determining that the age of the first segment is greater than the cutoff threshold, moving the first segment from the first high priority list to a first low priority list.
