I use Fastmail and have been very happy with them. They have been trying to deal with a DDoS attack from around the time this story broke. I initially didn't think anything of the timing, but given that this story is _literally about potentially criminal conspiracy_ it tickles the part of my brain that wants to indulge in other conspiracy theories -- e.g. someone connected to Google thinking "quick, we'd better make it look like a bad idea to try moving off GMail".
