It seems that my email to softlayer.com did miracles.
My site, after 4 hours and 11 minutes is back on the net.
They should tell people about such breaks, on their website. Domain DNS servers are crucial part of the net. They cannot just swithch off for many hours, like light in the "f..." room.
What do you think about Active-Domain services ?
Hope, we will survive till tomorrow, with them!
