Claim:
1. A method for controlling access to a data payload in a dead drop domain comprising a plurality of storage nodes connected by communication links, the method comprising: sending, to the dead drop domain comprising the plurality of storage nodes connected by communication links, a data payload and a payload write request to write the data payload to the dead drop domain; receiving, responsive to the payload write request, payload access information corresponding to a payload dead drop in the dead drop domain, the data payload stored at the payload dead drop; generating first metadata corresponding to the data payload, the first metadata comprising the payload access information and having associated first time-to-live (TTL) information specifying a first duration for the first metadata to persist in the dead drop domain; generating second metadata corresponding to the data payload, the second metadata comprising the payload access information and having associated second TTL information specifying a second duration for the second metadata to persist in the dead drop domain, the second duration different than the first duration; sending, to the dead drop domain, a first metadata write request to write the first metadata to the dead drop domain; sending, to the dead drop domain, a second metadata write request to write the second metadata to the dead drop domain; receiving, responsive to the first metadata write request, first metadata access information corresponding to a first metadata dead drop in the dead drop domain, the first metadata persisting at the first metadata dead drop for the first duration; and receiving, responsive to the second metadata request, second metadata access information corresponding to a second metadata dead drop in the dead drop domain, the second metadata persisting at the second metadata dead drop for the second duration.
