Are certificate renewals announced somewhere?

Hi,

Since last week 27th of August the SSL of Azure Service bus is renewed:

.

So the previous certificate expired and a new was put into place. 

Is this somewhere announced? That the certificates are going to change?

Another team here was locking to the previous certificate, so a whole flow didn't work anymore. They had to import this certificate to enable the workflow again.

In my calendar I can put a reminder, but I was wondering, maybe these changes are announced somewhere?

Thank you!
