In its history, it has never been down for more than 2-3 days though, so if it's ever down just shoot me an email and wait a day or so and check back

Are you sure it is up and running now? Alaska has made some changes and my alerts stopped coming. I just checked a flight on Dec 8, and LM Flighttracker told me no flights were available, while alaskaair.com does have flights available.
