Hi Cees! Have you changed your DNS recently? (was:Re: [Box-Admins] DNS server down)

As I still own squeakfoundation.org, I can repoint that. If anyone knows a spot where we can setup secondary DNS, preferably for free, ping me. Else, I’ll do some digging around to see where I can park it. I will probably need access to the primary DNS (do we still have a Hetzner host), will shout for help :-)

Both box3.squeak.org and box4.squeak.org have a DNS server installed, 
but they are not synchonized with box2 (our primary name server).
The plan was to host the two DNS servers on box3 and box4 (box4 as 
primary I guess), but I suspect that they are both in the same data 
center, so we could use a third server somewhere else.
