We have a scheduled maintenance related to EU1 WhatsApp API
Maintenance window: 2020-05-26 08:00 UTC to 09:00 UTC.
Impact: Clients may experience delayed delivery and receipt of WhatsApp messages during the maintenance window. Messages will be queued. The API will have a maximum downtime of 10 minutes during the window.
Affected endpoint: eu1.whatsapp.api.sinch.com
Planned maintenance of this endpoint occurs on the second and last Tuesday each month, between 08:00 UTC and 09:00 UTC.
Included in this maintenance window is the replacement of the Root CA SSL certificate for eu1.whatsapp.api.sinch.com.
We are not updating or changing the entity SSL certificate for eu1.whatsapp.api.sinch.com, 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.
