[Realtime-feed-users] GeoJSON Feed Update Frequency

[Martinez, Eric]

Hi James,

The GeoJSON summary data is cached for 60 seconds for the 1 hour, 1 day,
and 7 day data. The 30 day data is cached for 15 minutes unless you are
looking at 30 days of only the significant earthquakes data, then it is
still only cached for 1 minute. Both the FAQ and GeoJSON summary web pages
need to be updated for clarity/completeness and accuracy.

For reference, the source code that generates the feeds is all available on
GitHub, particularly with interest in cache times you may be interested in
looking here:

https://github.com/usgs/earthquake-event-ws/blob/master/src/htdocs/summary.php#L102

If you have any additional questions, please don't hesitate to ask.

Thanks,
     ~Eric.
