Impact on Existing Host-Mapped Subdomains - Zendesk Outage
Were existing host-mapped subdomains affected during the Zendesk outage?
Existing host-mapped subdomains were generally unaffected during the Zendesk outage unless their TLS certificates had expired. The issue primarily impacted new subdomains routed through the affected CDN.
The outage was due to a malfunction in the CDN vendor's API, which prevented the updating of TLS certificates. This meant that while existing subdomains remained functional, new domains faced errors due to unvalidated custom hostnames.
