It is recommended that anyone using the old URLs make relevant changes
before Friday 27th May, 2011, at which point the old URLs will no longer
be available.

The new URLs are accessible with immediate effect.

Why the change?

These changes are being done to keep reference data files dynamically
updated with the BATS Europe symbol reference database at all times.
