It’s always DNS (bad memories showing up)

I think that is good to make simple questions sometimes because sometimes a google search isn’t enough to solve all of your doubts and questions. Sometimes you need to talk to more experienced people to learn things you’ve never heard of and discover more things on your own.

Looks like it is very stressful to work when you need this amount of availability, even more with the pressure that a little error can cause giant consequences.

Thanks for your answer!

Whoa, there are a lot more factors than i was thinking.

I am not planning to host a site, I was just thinking about it and how complex it would be to make such website and well, makes sense to only the biggest sites on the web have that level of availability.

Thanks for your answer and for your time!
