TLS certificate status: Expired
Percentage of SSL/TLS servers with certificate status Expired certificate. Showing percentages by IRC server software.About this test result: The certificate is expired.
Note on statistics:
- There is a difference in the gathering of TLS servers between 2017-2019 and 2020-onwards, see SSL/TLS statistics on the data page.
- For certificate validation errors, OpenSSL (s_client) returns a single error only, so only 1 of the errors is picked even though one server cert could have multiple errors.
- However, from 2023 onwards "Expired" is detected even when there are other errors (eg. Unknown CA).
