CO2 Science experiences "a terrorist-like Denial of Service"

Here:

A week ago we experienced a terrorist-like Denial of Service Attack on our website that rendered it inaccessible to patrons. Unfortunately, the company that managed our website was unable to stop the attack, and we had to make the decision to host our website elsewhere. Moving our website to another server is not a simple task and must take place in stages. For now, only the current weekly issue of CO2 Science will be accessible, followed by a gradual return to full website access and functionality in the coming days and weeks.
