DETAIL: We are experiencing a distributed denial of service (DDoS) attack on the services, which is currently overloading our firewalls.

RESPONSE: Our technical team are working hard to get this attack under control and return full service to all customers. We hope to have this completely resolved shortly.

UPDATE: We've managed to block what appears to have been three different types of DDoS attack. Combating the three attacks has taken us longer than expected but we appear to have got them under control as of 11:35 but continued to experience minor issues until 12:32 BST (GMT +1).
