In a word, bollocks.

The domain in question fails to validate because it has no DNSKEY records which match the DS record for that domain in its parent. Returing a SERVFAIL in these circumstances is emphatically not a protocol violation. As a matter of fact, it’s a protocol *requirement* to do just that.

Now google’s resolving servers might well be causing “systems to break” because they’re doing The Right Thing. That’s not google’s fault. It’s not their problem either. Bad things happen when people misconfigure their DNS servers/data or fail to look after them properly. As the holder of xn--e5h.com has done.
