Example methods and systems for determining failure modes of balloons within a balloon network are described. One example method includes: (a) determining at least one cohort balloon of a first balloon, where the first balloon is operating as part of a balloon network and where each cohort balloon shares at least one property with the first balloon, (b) determining at least one expected failure mode based at least in part on at least one failure of at least one cohort balloon, (c) determining a predicted failure mode of the first balloon based at least in part on the at least one expected failure mode, and (d) causing the first balloon to operate within the balloon network based at least in part on the predicted failure mode of the first balloon.
