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.
