Load Shedding
/loʊd ˈʃɛd.ɪŋ/ · Noun · Development · Origin: 2004
Definitions
The deliberate rejection of a portion of incoming requests when a system is under extreme load, preserving capacity to successfully serve the remaining traffic rather than failing for everyone.
In plain English: When a system is overloaded, it intentionally turns away some users so the rest can still be served properly — like a bouncer limiting how many people can enter a packed venue.
Example: "During the flash sale, our load shedding kicked in and started returning 503s to non-authenticated users so that customers with items in their carts could still check out."
