An hour is a bit of an exaggeration. I come in to work early every day, and sift through operational alerts/clear out easy tasks in that hour. I do this while eating cereal, making and drinking coffee, etc. If I have some time left over, I read the news (usually finish everything up in about 20-30 minutes).

Of course, we do a technical rotation, and there's a lot of small tasks to do, most of which require a very quick grep of the logs.
