[dns-operations] Query to g.root-servers.net/192.112.36.4 timing out

[George Barwood]

When running the verisign tool

http://dnssec-debugger.verisignlabs.com/uk

quite often (maybe 1 in ten times) it reports timeouts when querying g.root-servers.net, e.g.

"Query to g.root-servers.net/192.112.36.4 for ./DNSKEY timed out or failed"

I think this has been going on for some time.

My guess is that there may be some kind of network/firewall problem with g.root-servers.net,
although I don't see timeouts when I query directly.
