You might have noticed that we have had quite a few drop outs over the last few days. It has nothing to do with DDoS attacks, but instead we appear to have an issue with the hardware that the site itself runs on. We have contacted the host and are scheduled to have our motherboard replaced over the next few days which will hopefully rectify the problem. So if we are not around for a few hours there should be no cause for alarm.
Edit: This was solved, thanks all for your patience.
