POST-MORTEM: Root cause of the issue has been determined to be a new spam filtering firewall which was in testing, and which was exposed to our internal network prematurely (and was only meant to reside within a test environment). The device’s network configuration was not compatible with our internal production network, resulting in duplicate IP addresses existing on the network, which in turn created routing issues. This root cause was identified and corrected reasonably quickly, however additional lengthy steps were required on the network to clear the invalid configuration. In the short-term, internal hardware testing and implementation procedures will be reviewed for accuracy and adherence.
