Important technical information

We would like to inform users of the CNB website that automatic redirection of url addresses previously used on the CNB website to currently valid ones will cease to operate as from 1 September 2008. This concerns addresses beginning with wdb.cnb.cz/... and those beginning with www.cnb.cz/cz/. All currently valid addresses begin with www.cnb.cz/cs/ or www.cnb.cz/en/. We ask users, especially those who download exchange rates in txt format, to take this change on board in their automated systems.
