MARS updates failing due to certificate error (FYI)

All our MARS devices started failing IPS signature dynamic updates today due to a certificate error.  I assume this has been updated using a root which isn't in the MARS.  I've opened a TAC case to confirm the change was intentional.  Assuming it is, all MARS devices in the field will need manual attention before they continue updating.  I will provide an update later today.

Error:
