Tip of the day. When there's network maintenance going on, don't try to test your work remotely (like from home at 11pm on a Friday). Why? You application will behave as if it's on crack. You'll wonder why. You'll debug. You'll become completely mystified.
Then you'll remember the announcement from earlier in the week. The one about the pending network changes on Friday night.
At least I didn't waste too much time.
It must be time to go read weblogs.
