Problem resolving a domain

I have noticed this, too,
The problem seems to be related to edns - disabling edns for the upstream
servers looks to resolve the issue, this can be seen with later versions of
dig -
$ dig *+noedns* +timeout=1 +retries=0 IN A myapplication.glbaa.barclays.com.
@ns21.barclays.com.
I have config along the lines of -
server 157.83.102.245 {
edns no;
};
for each of the problematic upstreams. I contacted Barclays a few months
ago about this, but never got a solid response.
