The earthquake map widget doesn't display the current data anymore.
Would be great to get it back working, but I don't know the technology
behind the scenes.

I assume that there might be an serverside change and contacted USGS.

The response is as follows:

Q:Did you recently change servers or api (within the last week or so) ?
A: Thank you for contacting the USGS. We might have. The Earthquake Hazards Team changed a bunch of the scientific applications around on March 1, but I do not think they messed with any of the real time feeds
