Latest update from Proton Drive

The issue is fully resolved now. The downtime was unfortunately caused by an issue at Cloudflare, one of our upstream service providers, so we had no control over the incident or its resolution. Cloudflare unfortunately dropped traffic from a small number of IP addresses at random, which made it impossible for some users to connect unless they used a different network or IP address. The impact was limited to a small number of users, but disruptive to those who experienced it. Due to Proton's built in redundancy, no data was lost, although some emails may be slightly delayed. We are now engaging with Cloudflare's senior management to ensure that such an incident does not repeat, and are taking additional remedial steps.
