EPEL GPG KEY issues

edit

Is there are issue accessing dl.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL-7 from the UK? I have tried from a number of different locations however this either completely times out or takes a very long time. Errors are as follows: -

STDERR: warning: /var/cache/yum/x8664/7/epel/packages/R-core-devel-3.4.0-2.el7.x86 64.rpm: Header V3 RSA/SHA256 Signature, key ID 352c64e5: NOKEY GPG key retrieval failed: [Errno 12] Timeout on https://dl.fedoraproject.org/pub/epel... : (28, 'Operation timed out after 30001 milliseconds with 0 out of 0 bytes received')
