Obviously, it's due to current unsponsored deployment.
* For a package of several kB, the first bytes (actually ~800B, measured) are
  not meaningful
* Our (mirrors@d.o) is to have http.d.n made official so that we can have an
instance like on each continent, then use GeoDNS, like security.d.o mirrors, to
achieve 2 goals: avoid SPOF, be closer to users.
