So can somebody explain to me, how come that the bets kept on flowing even with the domain down (that's a fact, right?)? DNS caching? Are there alternative routes to using this service besides satoshidice.com?
What is there to understand? don't you send a bet to a Bitcoin address? the betting system relies on Bitcoin network only. The satoshidice.com frontend website serves only to see some stats and to copy down the betting address, which is also available elsewhere like blockchain.info
