Apple Push Notification service server certificate Was the update published as scheduled?

I tried below at 2:00 PM on 21/01/2025(JST).

Apple Push Notification service server certificate update

I followed above, a new server certificate: "SHA-2 Root : USERTrust RSA Certification Authority certificate" was added to my push server, but a certificate error occurred and push notifications could not be sent.

So I refered this article,Instead of connecting via DNS name resolution at api.development.push.apple.com, I fixed api.development.push.apple.com to "17.188.143.34" in /etc/hosts, I could push notifications with the new server certificate. (I got this IP(17.188.143.34) from this airtcle)

From this, I suspect that Apple had not yet updated the APNs certificate (CA) for the Sandbox environment as of 2:00 PM on January 21, 2025 (JST). Was the update published as scheduled?

Due to the US holiday on the 20th, the deployment is being delayed by one day. All sandbox servers are expected to be updated to the new root certificate by 23:59 PST On January 21st, 2024

It had been recommended that you do not replace the old root certificate with the new one, but add it to the trust store, so both root certificates would be available to be used as the opposite end needs it. That is the way for a smooth transition.
