On Wednesday, September 2nd, between 8:00 am and 9:00 am CEST (UTC +2; EDT -6), we'll conduct scheduled maintenance to strengthen our infrastructure. This maintenance will be batched into two separate downtime windows. The first will last up to 30 seconds and will cause complete unavailability of all Proton services. The second will last up to 30 seconds; and during this time, Mail users may experience availability issues (e.g., inbox will appear read-only). Thank you for your understanding!
