The last example is peterhost.ru. Hosting company with 24/7 support. And all system administrators work there from 9 to 19 on working days. And if my question for the support goes beyond the framework of the FAK, then I can only wait, what I do for the second day.
Why national? Yes, just most often we meet this. We are chasing after competitors and proudly posting on the site - 24/7. One thing pleases - we have become polite!
