It kept me at 500 feet but I found a hole over the approach lighting and was able to land.

So, what do you do if the GS is said to be out but really isn't and isn't notam'd out of service?
A lot of times, the Glideslope will be notamed out of service while someone is working on it, or when one of the components of the GS is inop. The best way for them to work on it may not include shutting the thing off. Sometimes they need to test the integrity of the signal from ground based means, and you can't really do that while the thing is working. I've followed it in VFR a couple times at ACE when the glideslope was called inop, and didn't really have a problem, no noticeable differences. However, I'm sure as hell not going to trust my life to a piece of equipment that may or may not be functioning properly.
