ProtonMail On Battling A Sustained DDoS Attack
Encrypted webmail provider, ProtonMail, has been fighting a wave of DDoS attacks since November 3 that, by last Friday, had taken its service offline for more than 24 hours. At the time of writing the attacks are still coming.
They have included what ProtonMail co-founder Andy Yen described as a “co-ordinated assault” on its ISP that exceeded 100Gbps and attacked not only the Swiss datacenter but routers in various locations where the ISP has nodes — taking multiple services offline, not just ProtonMail’s email.
