ProtonMail, the Geneva-based encrypted email service that was developed by CERN scientists, was taken off line on Tuesday 3 November by what the company describes as an “extrememly powerful DDoS attack”.
In terms of scale of the attack, our IPs were targetted, then our datacenter in Switzerland, then the ISP that provides data to our datacenter. So the attack is very powerful and ongoing.
This is a problem i believe the safe network can solve from day 1; DDOS resilient encrypted mail app. For now bitmessage is the best alternative imo.
