Things I have learned - Part 5
Short and sweet today: There is always a point of failure, between your redundant, non-single-point-of-failure components You know, the single cable or switch that connects your VRRP firewalls, which on failure results in two machines that both think they're master. Or the RAID controller that connects to both disks in your RAID-1 mirror, which on failure takes out both disks (or worse, corrupts data on them).
