[tor-relays] BBC iPlayer blocked for UK middle relay operators?

Is anyone else running a relay in the UK having issues accessing BBC iPlayer from the same connection? For the last 6 weeks or so now I've been getting messages telling me I'm 'outside the UK' when I'm in London, and my IP address clearly resolves to show that.

Just wondering if the provider BBC use for iPlayer might have started just blocking all Tor IPs recently - including middle relays.
