Re: why is it your problem?
It's the same in UK (or at least England) for most primary schools. Some have a local authority IT guy who may get there to sort things out. It depends on the cost and quality of the contract since it's usually outsourced by the LA. Cheaply. And that's an improvement from what it was when I started teaching in the 80s. I got back into doing computery stuff having been an amateur tinkerer previously because there was no one else doing it. I assisted and took over from a deputy head when he got promoted. Training local schools to use their newly arriving PCs. And the situation didn't improve for over a decade - but the number of computers increased dramatically. And even today most schools ( this is where I started this comment) will wait a long time for something to get fixed if there is no scheduled visit.
