Certificate Rotated in Osaka Regional Ingress Rest API

On October 23, 2023, the certificate for Osaka Regional Edge Ingress of the Rest API products (e.g. chat.osaka.*.twilio.com) has been rotated successfully. The root, intermediate certificate (ICA) has been renewed, as well as the certificate serial number has been changed. Such updates are common practice and do not impact customers that are using Twilio's services unless you are pinning certificates or are managing them manually.

For customers who are pinning certificates or are managing them manually, please add these new certificates now, if these have not been added already when the communication was sent in September 2023.
