WorldPay disrupted with Denial of Service Attack

Published on: 13/04/2006

NOTICE FROM WORLDPAY

Access to WorldPay payment and administration systems continues to be disrupted due to a large scale Distributed Denial of Service (DDOS) attack, by a unknown third party. We are processing payments but fewer and more slowly than we normally would.

The attack began on Saturday (02/Oct/2004) evening at about 18:00 BST. WorldPay's payment and administration systems are working safely and securely, but the networks around them are being systematically flooded with requests for our service on a huge scale. During such an attack different customers will be affected at different times and to varying degrees. If a first attempt to make a payment does not succeed, please advise your customers to try again.

You may be aware that other major companies around the world have been subject to Distributed Denial of Service (DDOS) attacks recently. While such attacks can be anticipated to some extent, it does take time to identify and deal with the exact nature of a particular attack which can also change several times, over several days.

WorldPay would like to emphasise that the integrity and security of your data has not, in any way, been compromised.
