 It's clear that for all of the datasets, these latencies are much longer than the latencies that users of Internet-based communication tools are used to.
 Many activities that we're used to coordinating through such tools would be seriously disrupted by communication latencies on the order of days or weeks.

 For each dataset, we can find the minimum time-to-live that achieves the same level of reachability as an unlimited time-to-live.
 This tells us the *maximum path latency* of the dataset.
