Thread:Extension talk:Maps/Geocoding stopped working

Installed yesterday, everything seemed to be working fine. I created lots of maps via a widely-used template, and they all displayed correctly.

Today, invocations of #geocode fail with "Fatal error: Parameter location must be a valid location" (example: ). Maps are blank, with a similar error (example: ). Maps work with explicit coordinates (example: ).

The failures started after I ran runJobs.php. Maybe this triggered too many requests to the geocoding service, causing me to be blocked? Is there a quota? Do I need to set up an account? Can't find good documentation about this.

This may be the same as the error reported below, "Parameter coordinates must be one or more valid locations", but I didn't want to make that assumption. Configuration: MediaWiki 1.20.3, PHP 5.3.15, Maps 2.0.1, Semantic MediWiki 1.8.0.4.
