Query failed (timed out)

[Daniel Stirnimann]

federate.secure.barclays.com. is a CNAME pointing to
federate-secure.glbaa.barclays.com

The authoritative name servers for federate-secure.glbaa.barclays.com
are broken:

glbaa.barclays.com.	900	IN	NS	ns24.barclays.net.
glbaa.barclays.com.	900	IN	NS	ns22.barclays.net.
glbaa.barclays.com.	900	IN	NS	ns23.barclays.com.
glbaa.barclays.com.	900	IN	NS	ns21.barclays.com

They only seem to respond to A, AAAA queries. Everything else times out.
Queries with EDNS Cookies (RFC7873) timeout as well.

You should be able to work around this by adding this to named.conf

server 157.83.126.246 { send-cookie false; };
server 157.83.102.246 { send-cookie false; };
server 157.83.126.245 { send-cookie false; };
server 157.83.102.245 { send-cookie false; };
