Keycard access, terminal server access, and other management protocols should be independent of that type of traffic as it can affect or be affected by bandwidth and blackhole route issues.
Absolutely correct.. how the hell should bad bgp route Advertise to the outside world effect the internal network devices taking to each other? No way in hell that should impact the local keycards access unless a moron designated the network
If this could lock them out of the building then a wan outage of any kind that would do the same
I heard an internet guru explain that it was in fact a systemwide BGP update foul up. And because Facebook keeps everything inhouse, including even their security system, all the keycards stopped working as well. Rumor was they were using angle grinders to gain access to their master servers.
