The anti-genetically modified activist group known as Take the Flour Back failed to gain access to the GM wheat trial they had publicly criticized this weekend. The group had announced it would break in to Rothamsted Research to destroy a field trial of wheat variety engineered to repel aphids on Sunday.

Hundreds of protesters showed up at the research center, but security around the site was increased in preparation of the demonstration. On Friday, an order was issued to ban protestors from entering the site. 

However, on the same day that the protests were being held, servers at the research center were attacked. Its Web site was taken off line by a distributed denial-of-service (DDoS) attack.

A spokesman for the institute said the Web site was down from Sunday afternoon until Monday morning. It is not known who is responsible for the cyber attack. It is unknown if Take the Flour Back was involved.
