Just joking...A little sarcasm to match yours.   Heh

How did it take down the whole network, just bandwidth?

Had an issue a while back where the wife was using a 3rd party download program for work that was apparently not well designed, it made the WiFi just stop working.   Once the app was stopped it was back to normal.

I'm not sure, I'm not an IT guy I just play one in my home.  It might be a bandwdith issue, but I've done other updates before.  I suspect it has to do with my work laptop and dock network security settings as well.  If I connect to VPN before the mac mini my son uses for school, the router craps out and have to hard reset.
