Just before 4 PM today, a core router management module failed. The unit did try to fail over to the backup but it was not a complete cut over and some services were disrupted. We attempted to reboot the module but that caused a more massive failure in the chassis for less than 1 min. The bad module has been removed and service has been restored. We are continuing to troubleshoot the first problem with the vendor.
