Can I ask a pretty newbie question - how is BGP connected to IP, TCP and DNS protocols? Is it sitting "below" them, "on top" of them, or is it somewhere else?

BGP and DNS run on TCP which runs on IP.

For what it's worth, this is quite a vulnerability in the internet's routing system. It's also the reason Youtube went offline after Pakistan was deliberately announcing the wrong routes a few years ago because it didn't agree with some videos being broadcasted by Youtube. http://www.ripe.net/internet-coordination/news/industry-deve... http://news.cnet.com/8301-10784_3-9878655-7.html

This worries me. Am I right in saying a malicious party could actually take down the internet with this?

Earlier quoted context omitted.

That only makes it more likely that what was said has a semantically correct meaning though (or is that what you meant?).

He meant that there is literally only one definition for literally. Any other use of the word cuts away at its meaning (like what happened in that context).

Not really. It is literally something that binds the internet together (i.e. one of the common definitions of the word glue).

Malicious party? It already happened by accident. http://www.renesys.com/blog/2009/02/longer-is-not-better.sht...

They would have to be a 'trusted' malicious party. But in theory, yes. I'm sure it would be reverted very quickly though.

Am I? Not snark: if I'm misunderstanding this, I truly want to know. I'm in central US, CST, and the article gives PST. That conversion has always just been +2 hours.

As I read it that was 18:24 yesterday in PST, or 02:24 today in UTC. The use of "today" may just be sloppy dating-- or it may reflect that it was today for most of those affected.

My guess was that he wrote the article yesterday, but didn't publish it until today. It's not a big deal, was just curious.
