So after that list (called a consensus) is voted and agreed upon, they distribute that list. One hour is assigned to get the list to mirrors, so that not everyone has to hammer the authorities to get their list of nodes.
And the next hour is used for clients to fetch that consensus
so you see, it takes quite some time until your address is distributed
that is unfortunate, and we're working on designs to get relays to clients much quicker
but it's not easy.
