Liverpool, Robin Hood and Durham Tees Valley are now majority owned by the Vancouver Ports Authority & a Canadian Pension fund.
It could be that the new owners are in the process of changing them all into a standard format (which they weren't before).
As I said before, there was a server problem earlier which the respected websites social network pages stated to their followers.
As for a standard format, well they have been in standard format for while as far as layout goes. The only difference to each would be the colours to match the logos and individual services.
