We are not updating or changing the entity SSL certificates for the FQDNs above, including the certificate authority's intermediate certificate (expiring on Dec 2030).

We are only updating the certificate authority's root SSL certificate that is expiring this coming 30th May 2020.

If your TLS client is validating only the entity SSL certificate and your TLS client is chaining it against your existing trust store that already has the updated certificate authority root SSL certificate with the DN: "Subject: C=US, ST=New Jersey, L=Jersey City, O=The USERTRUST Network, CN=USERTrust RSA Certification Authority" expiring on 2028 or 2038, then you do not have to do anything in response to this notice.

Download ONLY the updated Root CA SSL Certificate files here: (Link) or
Download the current individual Entity SSL Certificate Chain with the Updated Root CA SSL Certificate included here: (Link)

We appreciate your patience and apologize for any inconvenience experienced during this maintenance period. If for any reason the maintenance is extended or cancelled we will advise you accordingly.

Please contact support@sinch.com should you require further information or assistance.
