StartCom: OCSP responder often returns "unknown" for recently-issued certificates

RESOLVED Start Commercial (StartCom) Ltd.
AI Summary

The StartCom OCSP responder frequently returns 'unknown' for recently issued certificates, causing connection errors for users. This issue arises when certificates are replaced shortly before expiration, leading to delays in the OCSP server's updates. While some browsers may handle this response differently, Firefox's strict rejection of 'unknown' responses can render websites unusable. The case highlights the need for StartCom to improve its OCSP response times to avoid user disruptions.
