Suddenly, every .com domain failed DNSSEC validation (regardless of it is signed or not), and normal resolving fails randomly with DNSSEC disabled, for example all youtube videos say "A error occured". Manually resolving urls with dig or nslookup randomly gets a SERVFAIL when DNSSEC is off, else it Always get a SERVFAIL.
Here is the log with DNSSEC enabled: http://pastebin.com/9maHnk6L

What could be the cause of these problems? Theres no problems with the upstream ISP Connection, I checked Everything. Is there some root server issue?
Im running dual-stack with IPv6 from he.net
Is there some global internet issue or is the problem at my side?
