Following ongoing investigations, we can now confirm that these problems have been caused by a substantial denial-of-service (DoS) attack against the website.
A DoS attack is an attempt to make a computer resource (in this case, the PCS website) unavailable to its audience by overwhelming the website with 'false' traffic. This traffic does not consist of legitimate visitors.
It is important to note that this has had no effect on the security of the information we hold, such as membership data.
With our web development company, we are doing all we can to minimise the effects of these attacks on our website and to ensure that normal service is resumed as soon as possible, so that visitors can find out the latest on our campaign for an alternative to government cuts and this year’s annual conference.
We thank members and visitors to the site for their understanding and patience during this period, and apologise for any inconvenience caused by this illegal and unprovoked attack.
While access to the site is disrupted, you can continue to find out the latest updates from us by:
