Hi Bruce,

Not to be a wet blanket,

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

but DNS is mildly hosed.

ping xymon.com
PING xymon.com (90.184.111.80) 56(84) bytes of data.

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

ping www.xymon.com
ping: unknown host www.xymon.com

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.

Henrik
