John-
I agree. We all should/would have seen
even a minor outage. That's what makes the event from early this week a rather odd event.
I have personally observed GPS jamming events from truck drivers trying to prevent being tracked. But those events are very localized it seems and are well bounded.
I cannot speak for others, but I am on
a presumption/ theory for our vendor supplied gear that the GPS engines may not have dealt very well with SVN 4 being tagged as "not for use" on
Sept 3 & 4. Just a theory from an RF guy since I have no other explanation why some gear had issues yet 99% of us Time-Nuts never noticed an issue.
Oh well......
