asking the office DNS the same question i get 51.38.69.52, asking 9.9.9.9 it gives me the same IP as the office DNS. Finaly asking google or 8.8.8.8 i also get 51.38.69.52
So i think their record is borked.
Nobody cares; the reality is if you use CF DNS, shit don't work.
I've switched to archive.org because archive.* is broken. For stuff that .org doesn't have, there's always the Tor version. The Tor address seems to be more responsive as well, so that's nice.
