Methods and systems are disclosed herein that may help to provide location-aware caching and/or location-specific service profiles in a balloon network. An exemplary method may be carried out by a balloon that is at a location associated with the first geographic area in a balloon network that includes a plurality of defined geographic areas, and may involve: (a) determining that a location-aware cache of a balloon should be updated with user-data associated with the first geographic area; and (b) in response to determining that the location-aware cache should be updated: (i) sending a location-aware cache-update request; (ii) receiving, as a response to the location-aware cache-update request, user-data that corresponds to the first geographic area; and (iii) storing the user-data that corresponds to the first geographic area in a location-aware cache of the balloon.

The method of claim 1, further comprising: determining a direction in which the balloon is travelling; anddetermining that the direction in which the balloon is travelling is towards the first geographic area, wherein the determination that the location-aware cache of the balloon should be updated with the first data is further based on the determination that the direction in which the balloon is travelling is towards the first geographic area. 4. The method of claim 1, further comprising: determining a direction and speed of travel for the balloon; anddetermining that the balloon is travelling towards the first geographic area with at least a threshold speed, wherein the determination that the location-aware cache of the balloon should be updated with the first data is further based on the determination that the balloon is travelling towards the first geographic area with at least the threshold speed. 5. The method of claim 1, wherein sending the location-aware cache-update request comprises sending a location-aware cache-update request to one or more other balloons in the balloon network, wherein the first data that corresponds to the first geographic area is received from one or more of the other balloons. 6. The method of claim 1, wherein sending the location-aware cache-update request comprises: sending a location-aware cache-update request to a ground-based station that is associated with the first geographic area, wherein the first data that corresponds to the first geographic area is received from the ground-based station. 7. The method of claim 1, wherein the border area comprises a border between the first geographic area and at least a second geographic area, the method further comprising; based at least in part on the determination that the balloon is located in the border area, removing second data that corresponds to the second geographic area from the location-aware cache of the balloon. 8. The method of claim 1, wherein the location-aware cache-update request further comprises an indication of a rate at which the first data should be sent to the balloon. 9. The method of claim 1, further comprising: determining a network traffic level; anddetermining the rate at which the first data should be sent to the balloon based on the network traffic level. 10. The method of claim 1, wherein the border area further corresponds to at least one second geographic area, the method further comprising: initially determining that the balloon is at a location in the at least one second geographic area location, wherein the location is outside of the border area; andsubsequently making the determination that the balloon is located in the border area;wherein the determination that a location-aware cache of a balloon should be updated with first data associated with the first geographic area is based on the subsequent determination that the balloon is located in the border area. 11. A system comprising: a non-transitory computer-readable medium; andprogram instructions stored on the non-transitory computer-readable medium and executable by at least one processor to: determine that a balloon is located in a border area corresponding to a first geographic area in a balloon network comprising a plurality of moveable balloons, wherein the balloon network comprises a plurality of geographic areas that includes the first geographic area;based at least in part on the determination that the balloon is located in the border area, determine that a location-aware cache of a balloon should be updated with first data associated with the first geographic area; andin response to the determination that the location-aware cache should be updated: send a location-aware cache-update request;receive, as a response to the location-aware cache-update request, first data that corresponds to the first geographic area; andstore the first data that corresponds to the first geographic area in a location-aware cache of the balloon. 12. The system of claim 11, wherein the location-aware cache-update request message is sent to one or more other balloons in the balloon network, and wherein the first data that corresponds to the first geographic area is received from one or more of the other balloons. 13. The system of claim 11, wherein the location-aware cache-update request message is sent to a ground-based station that is associated with the first geographic area, wherein the first data that corresponds to the first geographic area is received from the ground-based station. 14. The system of claim 11, further comprising program instructions stored on the non-transitory computer-readable medium and executable by at least one processor to: in further response to determining that the location-aware cache of the balloon should be updated with first data associated with the first geographic area, remove the first data that corresponds to at least one other geographic area from the location-aware cache of the balloon. 15. A computer-implemented method comprising: in a balloon network comprising a plurality of balloons and a plurality of defined geographic areas, a first balloon determining that first data from a location-aware cache of the first balloon should be provided to a second balloon that is at a location associated with a first geographic area of the balloon network, wherein the first data is also associated with the first geographic area, and wherein the determination that the first data should be provided to the second balloon is based at least in part on a determination that the second balloon has moved into a border area corresponding to the first geographic area; andin response to determining that the first data should be provided to the second balloon: sending a location-aware cache-update message to the second balloon, wherein the location-aware cache-update message indicates that the second balloon should update a locate-aware cache of the second balloon with first data corresponding to the first geographic area; andinitiating a transmission to the second balloon of the first data corresponding to the first geographic area. 16.
