An online system performs load shedding in case of system overloads. The system maps each request to a tier and a cohort. The tier is determined based on a type of request and the cohort is determined based on the user. Each tier includes multiple cohorts. The tiers and cohorts are ranked by priority. If the system determines that the system is overloaded, the system determines a threshold tier and a threshold cohort for load shedding. The threshold tier and threshold cohort indicate a threshold priority of requests that are processed. If the system determines that the unprocessed request has a priority below the threshold priority indicated by the threshold tier and the threshold cohort, the system rejecting the unprocessed request. The system executes unprocessed requests that are not rejected.
