yum not working on EC2 Red Hat instance: Cannot retrieve repository metadata

Question

For some reason yum has stopped working in my Amazon EC2 instance, located in the EU West sector. There seems to be something wrong with the path of the repo metadata, is this correct? I would be very grateful for any help, as my experience in this field is somewhat limited.

cat /etc/redhat-release:

Red Hat Enterprise Linux Server release 6.2 (Santiago)

yum repolist:

This is typically not necessary if you haven't mucked with the defaults.
