I've been using MMQGIS geocoding with Google Maps as the geocoder for a little while now, never any issue. As of yesterday, have gotten a few strange issues. I was unable to geocode at all yesterday, as it was giving me an HTTP 503 error when trying to connect to the google api. I figured this was just a result of maintenance or whatnot, so I used the openstreetmap geocoder, which is unfortunately far less accurate.
I tried using the google geocoder today, and it's even stranger, it successfully geocodes some of my addresses, but usually quits before I get to 10 of them, saying that I've reached my limit for the day. Not only is this impossible, it's also said this on different amounts of addresses geolocated (I've had 0, 2, 6, 7, and 10 so far). Has anyone else been having this issue, or does anyone have any possible solutions?
