Like EPLDCC said, DigiByte is truly decentralized (thanks, in great part, to the multi-algo coding), so when one user, even one "farm" goes down, the entire network is not affected. That is not the case with centralized networks (for whatever the reason they have become so, or why the devs planned them to be so from the beginning so that they could control and line their own personal pockets).

Nevertheless, even if a major part of the DGB network were to go down (here's another major advantage) the speed of confirmation and diff adjustments guarantees that the network will be back up and fully functional in practically no time at all (once the national power grid has been restored, or whatever caused the regional outage is fixed).

Here is a great synopsis from DigiReport #5: https://www.youtube.com/watch?v=-haCDqhaTqc

And, as I said earlier, there's a ton of information out there that answers 99% of your questions and I encourage you to take the initiative to begin researching and learning more about, not just the details of DigiByte, but everything about cryptocurrencies from the basic theory and ethos to the actual day-to-day real life operations (and issues).

@all newcomers, this last piece of encouragement can be extended to one and all - this thread is becoming extremely cluttered with useless commentaries . . . and you can imagine just how much more difficult it will be for new people to find the answers to their questions (like you are trying to do) the more cluttered and nonsensical the thread gets, right?
