CloudFlare was the first company ProtonMail called (with in 5 minutes of the DDoS starting). Unfortunately, they couldn't help ProtonMail. But, thanks to @rdl for responding to a txt on his cell phone at an inopportune time and mobilizing CloudFlare's sales and engineering teams to talk with Proton (during the company's retreat no less)!

For all the people getting nasty and arm chair quarter backing this on little to no information or trying to claim credit for things they did not do- understand that once you start working in venture funded startups pretty much everyone knows each other and many people have worked together before.
