On my home internet connection, I'm able to resolve most domains but none of the sub-domains of cloudfront.net resolve.
$ dig @8.8.8.8 resolver-identity.cloudfront.net
; <<>> DiG 9.9.5-3-Ubuntu <<>> @8.8.8.8 resolver-identity.cloudfront.net
; (1 server found)
;; global options: +cmd
;; connection timed out; no servers could be reached
However, I'm able to resolve it on TCP.
$ dig @8.8.8.8 resolver-identity.cloudfront.net +tcp
; <<>> DiG 9.9.5-3-Ubuntu <<>> @8.8.8.8 resolver-identity.cloudfront.net +tcp
; (1 server found)
;; global options: +cmd

What could be going wrong? How can work around this?
