This was substantially longer than seconds.
I was just on the phone to someone else in Sydney (not one of my 
customers) who was saying some of their stuff still isn't back.

I've heard some services were down for 15 minutes, some for well over an 
hour (and some sound like they're still down!)

Just curious. Normally this place lights up when there's a semi-widespread
