why does it take 60-90 seconds for a new node to get up?

Why is it that, if you set AutoBootStrap = false that it takes 60-90 seconds
for the node to announce itself?

I just want to understand what is going on during that time, and why that
specific timeframe (if there is a reason?)

The bootstrap has this delay to ensure that the information about the
new node is propagated to all nodes in the cluster. During the
autobootstrap writes have to go to the node that was responsible for
that portion of ring as well as the new node. In this way no writes
are lost.
