On Thursday, October 30th, 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 three separate downtime windows. The first two will last up to 30 seconds each and cause complete unavailability of Proton services. The third will last up to 2 minutes, during which Mail users will experience unavailability (e.g., read-only mailbox).
Thank you for your understanding!
