 Dirauths trust the uptime value reported in a relay's descriptor instead
 of doing some checking of their own to see if the reported value is
 plausible.This means it is cheaper than expected to mount a dos attack
 against a known hidden service by targetting the nodes responsible for
 storing its descriptor.
