Is Zoom SSL down right now?
This page answers whether Zoom SSL is down by checking the certificate zoom.us 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 Zoom SSL down right now?
No. At the last check the certificate zoom.us serves was valid, and it expires on 2026-12-29. Zoom SSL is up.
How does this page know if Zoom SSL is down?
A CertPost probe opens a real TLS connection to zoom.us 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 Zoom 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 zoom.us serves. For the full certificate detail, see the Zoom certificate status page.
