possible ORG problems, maybe?

I think I'm seeing problems performing recursive queries for names under ORG against tld[12].ultradns.net at the moment, which is causing resolvers without cached data to behave as if domains don't exist. It's not trivial to tell whether this is just a local problem, since all the authoritative nameservers for ORG are anycast instances (i.e. I might just be unlucky in that my local tld[12].ultradns.net nodes are behaving unexpectedly). Is anybody else seeing issues?
