DNS stopped responding about 20 minutes ago, giving "Server failed" error in nslookup command via terminal

The domain looks good, DNSSEC as well. I wonder if there may be an intermittent issue with the parent nameservers at dns.ripn.net - the registry does not seem to resolve either → cctld.ru - even the government domain does not seem to always resolve

When querying them directly, it works though.

@grenadiumdota, if you have a Twitter account, did you check there already?
