Larry,

What I suggested
has occurred recently and is likely to occur again.


When was the last widespread GPS outage (when was the first, for that
matter?)?

For a GPS outage to be significant to an airman, it needn't be wide
spread.

There is some information at these links:

Except local outages announced per NOTAM, since those don't
really count.
