Starting on Tuesday, November 3rd, 2015, ProtonMail was hit with an extremely powerful DDOS attack
. The attack was highly sophisticated and has taken ProtonMail offline for several days.
ProtonMail provides secure email to over half a million individuals around the world. Among these users are activists, journalists, whistleblowers, and other at-risk groups. In a day and age when our most personal data is sold to the highest bidder, our mission is to provide a haven where online privacy is respected and protected. With your support over the past two years, we have grown to become the world's largest encrypted email service.
Over the years we have faced pressure from laws, government agencies, and others. Now for the first time, DDOS attacks are being employed to stop us from protecting privacy. This fight will not be easy, but it is one that we must win. What is at stake is nothing less than the future of the internet, and we will never stop fighting to secure that future.
The attack conducted against us was the most sophisticated attack ever seen in Switzerland and displayed capabilities more commonly possessed by state sponsored actors. In order to defend against future attacks of this scale, we will need to utilize top-of-the-line solutions typically used by large companies such as Twitter, Facebook, etc.
These solutions are unfortunately very expensive and can run over $100,000 per year. Despite the cost, we have already begun to implement them, but this has placed an unexpected strain on our budget. Given our mission, and the capabilities of our adversaries, it is necessary to invest in these technologies to ensure that online privacy can never be denied. With your support, we can ensure that ProtonMail is better protected against future attacks and can continue to provide privacy for all.
