We have domain http://www.armtimes.com.
Almost always we can't access domain with www or without. Depends when we trying. Random time.
Also ping doesn't go. When I change in hosts file and setting (IP) armtimes.com, site open's normally..
Sometimes domain is working normally..
I think this is Domain related problem. What can be this?
Edit: Half of the problem was fixed: named was not started automatically after restart. I have started named service, and now work's. But I can't access site via www. Without www work's normally.
