Apologies to those customers affected by the disruption to some of our web and email serivces this morning.

We experienced a Denial Of Service (DOS) attack on our main firewall which sent an overwhelming number of requests through the firewall, causing slow response rates for web and email services.

The source of the attack has now been identified and dealt with accordingly.

DOS attacks can be particuarly difficult to deal with as there is no easy way to stop a request from hitting the firewall and even though we can block requests from specified IP addresses, the firewall still has to work out if to block the traffic or not.

For those of you who wish to find out more information on DOS attacks please take a look at the following information provided by Wikipedia

Once again, apologies for any disruption you may have experienced and thank you for your continued support.
