The best resource for understanding how nodes operate is just the source code that the majority of nodes on the network run: https://github.com/bitcoin/bitcoin. I don't share any email addresses here, sorry. There is a site chat room though: https://chat.stackexchange.com/rooms/8089/mempool

When each of those nodes comes back online, it will re-connect to other nodes on the network, and request data from those nodes about the most recent blocks. Each node will then validate that data for itself, and once that is finished, the node will be back in sync with the network.
