What's the name of that site you use to ensure that all the settings and systems etc. on your server are working okay? I can't remember. It gives you a sort of analysis on your nameservers, giving you cautions or warning on various things so you can spot what you could look into to get your website more secure or something. Sorry for the lack of quality description, but if I could describe it easily I could probably find it easily too. What I do know is that the results of a check will have a lengthy basic-looking table with the results in them.
