I see your point, but now I do not think it is FreeDNS fault. DNSChecker.org shows my domain name properly resolved worldwide, and so it has been for months. I also created a second subdomain just now, exactly as the non-working one, and was properly resolved within seconds at my work pc. So I do not blame FreeDNS, I think it is our internal DNS server that is messed up or even hijacked.
