a NIC would cause all that trouble? A $5.00 to $10.00 hardware, wow! |

| Who's the source ??
"...Connors, a chief in the office of field operations for the Customs and Border Protection agency" is commenting on the failure cause ?? Sounds like she heard what the problem was... Then again, why is the LA Times using her as the source of their information ?? |

I think this is the first time I have heard anyone trying to blame a "network meltdown" on a single NIC.... on a PC. Yeah right. Maybe if it were on a server. |

| ARP flood?
I've heard it said, but never experienced it first-hand, that a bad NIC can generate a substantial amount of ARP requests. It could have been poorly configured switches and an ARP broadcast storm that brought the network to it's knees, especially if it were machines replying to a "who-has/tell" ARP flood.
This is highly possible, regardless if it was a 'server' or a 'workstation'. |

| Sounds like a broadcast storm to me
Really sounds like a broadcast storm. Perhaps a switch went bad where it crapped on the spanning tree in such a way to cause a broadcast storm.
I've seen it happen even when all the preventing measures are implemented. Seems when a card decides to go crazy it takes the entire switch with it.

I agree it does sound like a broadcast storm. But even then they should have fixed the problem with in just a few hours. |

They never said the entire network relies on a single NIC.
A single NIC can easily kill a network if it is not configured for broadcast storm protection.
Nothing says the network had to be "relying" on the port in the one PC that went bad.
I mean, it even says in the article that a "domino effect occurred" that brought down other network cards. Why try to sensationalize it? |

| don't blame the NIC or the server
The failure was human-related, not hardware-related. Don't they have anyone there with half a brain that can figure out how to dual-rail, have a hot backup or, god-forbid, a SPARE NIC? Heck, anyone could have gone down to the local Best Buy or Fry's, picked up a new card and popped it in. We all know that hardware fails and part of a good design is to plan for the eventual failure of any key components, especially those in the critical path.
This is classic "cause/effect" excuse behavior. We are supposed to accept this as a valid reason - maybe even feel sorry for the poor FAA and move on. I bet the stranded passengers are not buying it. Akin to "I'm late because I missed the bus." it's standard bureaucratic BS. I think they take a course as part of their training.
Homeland Security is a farce and an oxymoron. The TSA is a joke and I don't think we're any safer today than we were 6 years ago. Unfortunately, the government equates huge process and excessive spending with security. Geez - we're totally broke here. |

What does this have to do with Homeland Security, other than the gratuitous "authorities believe there's no link to terrorism" that's thrown into reports of every little problem around the country? |

| No flying for me
This is yet another reason why, if I have to travel anywhere withing 2,000 miles of home, that I will just drive. The price would be about the same, and I have the luxury of stopping whenever and where ever I want, eating whenever I want, listening to loud music if I wish, using my cell if I need to, and seeing some sights.
If I had to travel over 2,000 miles, say to the East Coast from my West Coast state, Amtrak. Amtrak puts flying to shame.
