During the late 2000's I came across zonecheck, it did a lot of cool domain DNS based checks, but was written in ruby - which I knew nothing about (hehe still don't), but I managed to fudge it enough to make some tiny changes outside of the base code, this ran as a sub of ITS for a number of years, at some point later, I noticed zonecheck.org was a parking page on a registrars site, Zonechecks author, if he did control it once (can't recall but I'm sure he was zonecheck.fr and never .org) allowed it to drop, since my investigation showed this registrar had it for a couple years, and he never returned my Emails and some time later (2013) I noticed the domain was still vacant so snapped it up, I liked the name as it seemed appropriate for everthing here.

We're now in the tardis nearing the end of our journey where we've reached June 2021, most of the stuff on the main page remains relevant so needed no changes, but zonecheck was abandoned, and for some time replaced by zonemaster, a cleaner sleeker perl version (won't say I'm sad to see the back of the ruby one), I had been thinking about redesigning the website with a cleaner look for a while, so zonemaster appeared at the right time, I liked it, much cleaner, although written in perl, the web front end is heavily javascript dependant - it's only downside, but the end result is what you see today, its simpler to keep it in a sub directory, allowing the main pages testing stuff to be light.
