Looks like the debug page showed success, and then reverted to failure for timeout. Is the validation mechanism using a caching nameserver, or does it query the authoritative server every time? The latter could explain timeouts if the authoritative server has any sort of DDoS protection.
So far I haven't had issues with afraid.org except in the present case, so I'd assume DDoS limitation -- but that's also assuming BS hits the authoritative server, not a recursive server that would cache the answer and lessen the load on afraid. Would you perchance know?
