Not at all, I'd rather know about these problems.

that's my firewall dropping your ping. DNS is ok here...

but not here.

I think I've got it fixed now, but it may take 12 hours for the change 
to propagate out (DNS caching and all).

It's weird. I had
* an A record for xymon.com = 90.184.111.80
* an AAAA record for xymon.com = 2001:16d8:dda8:0:21c:c0ff:fec0:1875
* a CNAME for *.xymon.com = xymon.com
and that apparently breaks.

Even weirder, if I do a "dig www.xymon.com" I get an error (so that 
matches your experience). But if I do a "dig +trace www.xymon.com" it 
finds the IPv4 address just fine.

I think the wildcard CNAME is the culprit, but I am not quite sure why.
