I think I have an intelligent terminal; it's the mainframe that's *dumb*! Years ago, our system would crash a few times a week, and we'd be down for 10 minutes. Now, if we crash, we're down for hours. Doesn't happen as often, but when it does, we're dead in the water. I can still surf the net and create Word files and so forth, but when the front end system is down, it's a massive pain. If everything -- front end and Internet -- go down, we might as well all go home. Can't do a bleeping thing. That can really mess up your deadlines.
When the system freezes up, we all start yelling until it's fixed. It's not our IT guy -- he's great. It's the numbskulls where the mainframe is located. I don't think they give a crap about whether we're up or not, as long as their computers are working.
