Cafe Press outage was Denial of Service attack

Just found this posted at Cafe Press:

Hi Shopkeepers,

The CafePress site was down for several hours yesterday evening due to a DoS attack. Our team was on top of it immediately and was able to make the system available as soon as possible. Service was restored at approximately 11:30PM PST and was running smoothly until approximately 8:30 AM this morning. The team is on it, knows the drill and service will be restored as soon as possible.

A DoS attack is a denial-of service attack, an attempt by someone to make our site unavailable to our users. A DoS attack is a computer crime and violates Internet proper use policy as dictated by the Internet Architecture Board.

Needless to say we are appalled that this has occurred because of what it does to our community. We hope that you understand that for your protection we are limited to what we are able to discuss regarding this as it is a security matter.
