Does anyone know why a) every so often i get
"Name lookup failure for "cvsup.uk.FreeBSD.org": Host name lookup
failed" when i try to connect to cvsup.uk.freebsd.org and b) why even
after i get the name resolved I get this output from a dig +trace on the
servername
{root@prawn}#dig +trace cvsup.uk.FreeBSD.org
; <<>> DiG 9.3.2-P1 <<>> +trace A cvsup.uk.FreeBSD.org

Additionaly if you do a
for server in NS2.DOWNLOADTECH.COM NS1.IAFRICA.COM NS1.DOWNLOADTECH.COM
NS0.FREEBSD.ORG ; do dig a cvsup.uk.freebsd.org @server ; done
you get nothing from NS2.DOWNLOADTECH.COM
you get a recursive answer from NS1.DOWNLOADTECH.COM
and you get (as expected) an AUTHORITY SECTION from the other 2 telling
you where to look (the uk.freebsd.org nameservers)
I'm not a DNS wizard but i'd say something is wrong with
NS2.DOWNLOADTECH.COM and has been for a while now.
