Our apologies to those of you who tried to view our website on Sunday morning. This website its self was down. A possible cause was an overload of web requests (otherwise known as a denial of service attack). Under normal circumstances, even though our site is popular for a number of good reasons, it has very adequate resources to deal with normal peak demands (it can easily accommodate 10 times the normal peak requests). When this exceptional peak occurs in the early hours of Sunday morning something strange is going on. No data has been compromised. Other services were unaffected. We are looking into the reasons why this event may have occurred.
