Past RAIM outages

[rburnette]

I'm familiar with http://raimprediction.net, but I only know how to use it to check for future outages.

I had 2 GPS failures in an airplane I've been flying and I want to rule out anything environmental before I squawk with the avionics shop. Is there a way to see if I was flying through an outages at a time and location in the past?

Thanks in advance if anyone has any advice.
