I'm great.

Thanks for having me, Trevor, and thank you for that kind introduction.

Yeah, look, you're basically right there.

YGK is the best comparison for what went wrong.

What effectively happened was that they use what they call a timing server.

So it's sort of a GPS linked server that tells the rest of their network what the exact time is, kind of like the atomic clock concept, if you like.

Now, they're using a model called a sync server.

This is an old server which actually goes back about 20 years when it first came out and was a mainstay for about 10 years and then was discontinued around 2016.

And over that period, it was actually made by three different companies because the original manufacturer, Symmetricom, was sold to a company called Microsemi and then to Microship Technology, which might give you a bit of a clue as to how much support it gets.

Well, that's what we don't know.

This is the bit we don't know.

Were they in the process of actually doing a failover process at the time?

Because it's actually about the time of history when it is due for a reset.

These things were configured to last, I think it was 1024 weeks or maybe 19.7 years, depending on what measure you use.

So this is actually about the time from when those models first came out that you needed the reset.

What I suspect happened, I don't have any sources on this, by the way.

What I suspect is that they actually were trying to mitigate it.

They were attempting some kind of process and they stuffed up that process.

Right.

And this reminds me a little bit of what happened with Optus last year, where remember they took triple zero offline for a little bit to put a firewall in, but some dude in Chennai forgot to log it properly.
