I'm going to be working at home on Monday because our boiler is faulty. The valve is stuck or something so we can't get hot water without also getting hot radiators. When it's 21C outside and 14C at night, we don't want the heating on. But that's just one of those things.
So I'm at work running SQL queries on our largish database of around 3 million businesses. Again, no worries, I do this every day. But today it's rather dragging its feet, someone else is also running big jobs.
But a colleague needs a piece of work by Monday and the first time I did it, I got the wrong answer, mainly because there is no documentation outside of my boss' head and whilst I'm learning as much as I can, and writing it down as I go along, I don't know everything yet. But now I've sorted that out, I can run the query and even though I'll probably be here until 7, three hours past my normal leaving time.
And then we get a power cut. It lasts less than a second and our servers are on uninterruptable power supplies which give 20 minutes power. All it requires is the power switch to be reset. It's a big one in the server room. We just went and admired it. However, none of us, certainly not us analysts and not even the computer support people are allowed to touch it. It has to be an electrician because that's how the insurance works.
The electrician said he would be there in five but is presumably dealing with problems all over the building, like freezers in the canteen and PCs on the executive floor. And after ten minutes waiting, computer support has to take down the servers because he can still do it safely with the power that is left.
Naturally this crashes my job.
Now I'm sitting here waiting to be told when I can run it again and outside my window it is sunny and there is hardly a cloud in the sky and I'm usually home by now.
