Ajax DNS Down?

If you have ever needed to check dns propagation for yourself or a client, I am sure that you have used tools such as nslookup and possibly even dig. There are other tools, however, that you can use to check dns remotely or outside your network. One such tool can be found at www.ajaxdns.com which I have used religiously but for some reason today it seems to be under scutiny with editdns.com until sept 9 2011. As it is, there appears to be an acceptable alternative at: http://www.dnsbench.com/. I really hope that this can be resolved soon as I really enjoy ajaxdns.com
