ProtonMail, a free, open-source encrypted email service, has been under constant Distributed-Denial-of-Service attacks since at least June 30, according to a Reddit post by the company.
The attacks have also affected ProtonVPN, ProtonMail’s virtual private network, due to “shared infrastructure.”
The company emphasized that users’ data would be safe, despite the attacks.
“Despite the intermittent connection problems, no emails were lost, no data was lost, and no data was breached,” the company said. “In any case, we utilize zero access encryption to keep your data secure even if there was a breach.”
The company has kept their Reddit aware of the situation with time-stamped updates and has said that it is working with its DDoS protection provider Radware “to mitigate the attacks.”
According to an update today at 12:45 p.m., “Attacks are continuing, but are being mitigated and the services should be restored for most users. We are also making some hardware changes in our datacenter to improve resiliency.”
