503 server slow error on TRI layer

[jywarren]

I think we can modify our request to not trigger this error:

VM264 jquery.min.js:4 GET https://iaspub.epa.gov/enviro/efservice/tri_facility/pref_latitude/BEGINNING/41/PREF_LONGITUDE/BEGINNING/71/rows/0:300/JSON 503 (Service Temporarily Unavailable)

Origin 'https://publiclab.org' is therefore not allowed access. The response had HTTP status code 503.

What's weird is that it seems like some requests go through:

There's a bit on jQuery and CORS here: https://zinoui.com/blog/cross-domain-ajax-request

Actually i think the 503s may be:

Service Temporarily Unavailable
The server is currently unable to handle the request due to a temporary overloading or maintenance of the server.

Can we have this in GCI @jywarren @sagarpreet-chadha @ananyaarun ?

[jywarren]

That'd be great; perhaps we can brainstorm some ideas and prototype and test out ideas to see what can be done? And/or identify another source for this data that is more reliable?
