Let's Encrypt đã thông báo dừng Dịch vụ gửi email nhắc nhở gia hạn chứng chỉ SSL. Điều này có thể khiến nhiều người bỏ lỡ thời điểm gia hạn, dẫn đến website bị trình duyệt báo lỗi SSL.
Rất may là Vpssim đã tự động gia hạn SSL khi gần hết hạn.
Since its inception, Let’s Encrypt has been sending expiration notification emails to subscribers that have provided an email address to us via the ACME API. This service ended on June 4, 2025. The decision to end the service is the result of the following factors:
Over the past 10 years more and more of our subscribers have been able to put reliable automation into place for certificate renewal.
Providing expiration notification emails means that we have to retain millions of email addresses connected to issuance records. As an organization that values privacy, removing this requirement is important to us.
Providing expiration notifications costs Let’s Encrypt tens of thousands of dollars per year, money that we believe can be better spent on other aspects of our infrastructure.
Providing expiration notifications adds complexity to our infrastructure, which takes time and attention to manage and increases the likelihood of mistakes being made. Over the long term, particularly as we add support for new service components, we need to manage overall complexity by phasing out system components that can no longer be justified.
