Is Notion SSL down right now?
This page answers whether Notion SSL is down by checking the certificate notion.so serves, live and from outside, rechecked every hour. Most "is it down" pages ping the homepage; a broken or expired certificate is a different failure, and it is the one this page watches.

Common questions
Is Notion SSL down right now?
No. At the last check the certificate notion.so serves was valid, and it expires on 2026-11-11. Notion SSL is up.
How does this page know if Notion SSL is down?
A CertPost probe opens a real TLS connection to notion.so on port 443, the same way a browser does, and reads the certificate. The result is cached and rechecked every hour, so this reflects the healthy state seen at the last check, not a guess.
Is this the same as Notion being down?
Not always. A site can be reachable while its certificate is broken, or down for reasons unrelated to SSL. This page measures only the certificate notion.so serves. For the full certificate detail, see the Notion certificate status page.
