Our bullet-proof LAN failed. Here's what we learned

In my organization we manage almost all IT in-house, including the LAN, which is highly redundant. We have 35 Floor Wiring Concentrators around campus, each with around 300 active ports, and the concentrators have dual Gigabit uplinks to network cores in two data centers that are 300 meters apart. The data centers are linked by multiple 10Gb links, and each is connected to the Internet via two trunks that follow different paths.
