Our provider updated their system to ensure new SSL certificates were being properly served going forward.

Customer with a site with SSL certificates generated more than 3 months ago were returning SSL certification errors.


The SSL certification issue is now fully resolved due to the hosting provider resolving it on their end.


Gatsby’s Engineering Team successfully mitigated the certificate issue during the incident and installed a process to regenerate certs more easily to safeguard against similar, future incidents.


Root cause was identified as an operator error at our hosting provider. Our hosting provider has confirmed that the issue is resolved. Gatsby Engineering has installed a process as a redundancy to eliminate the potential risk going forward.
