The Thirty Meter Telescope (TMT) website,, was down for several hours on Sunday (April 26) as well as the Hawaii State Government's official website,  A group of hackers who call themselves ‘Anonymous' is taking credit for this cyber-hack that lasted for several hours on Sunday. In a recent tweet, the group Anonymous said “Nothing will ever justify the destruction of ecosystems; filthy money can never replace them. Stand with the Hawaiian natives against #TMT.”

‘Anonymous' is an international network of activists who have a history of hacking large websites including government websites, religious organization websites and large corporation websites. They hack these websites with something called ‘Distributed Denial of Service' (DDoS) which attempts to make a server or a network resource unavailable to users. This usually suspends the services of a host connected to the internet, causing the website to be temporarily unavailable. The tagline on the groups YouTube channel is, “We do what we want because we can.”

TMT spokeswoman Caroline Witherspoon confirmed the website server caused the website to be down for several hours.
