I am running 1.0.6. You can take a look at this page at testci.html.
There are some errors in the Firebug "all" listing, but they somehow seem to get resolved. In other words, the "file not found" errors don't correspond with the map that gets displayed.
The requests that return the "620" response are geocode requests, not cache read requests.
_xdc_._gg3rjfc4h && _xdc_._gg3rjfc4h( {
"Status": {
"code": 620,
"request": "geocode"
}
}
620 G_GEO_TOO_MANY_QUERIES The given key has gone over the requests limit in the 24 hour period or has submitted too many requests in too short a period of time. If you're sending multiple requests in parallel or in a tight loop, use a timer or pause in your code to make sure you don't send the requests too quickly.
