I am working late this evening. Thursday is my martial arts Leadership class too. When I got home tonight I had just enough time to change and eat before the call from the office came in. There is a large scale system update going on at work. I am partially responsible for the servers that are the authoritative source for all the updates. This is not a big issue, but I need update the authoritative servers also, which means a little juggling and a few extra backups so there is no down time in the system.
My actual time at work is about ten minutes with a 30 minutes break in the middle of that while I wait for other systems to go through there update. When all is done, unless there is a catastrophe, I verify everything works again and go to bed. I expect things will go smoothly, but I am online to handle any catastrophe, should one happen.
