Geocoder() is not working suddenly! Returns status code 502.

Found that the location search feature for my #LStreetMap (https://play.google.com/store/apps/details?id=hk.lookfor.lstreetmap) does not work suddenly today. There is a line of code which using geocoder.getFromLocationName() returns no result from Google.

To trace the problem, I read the LogCat and I see followings:

12-24 01:10:25.679: I/GCM.HTTP(1490): Last HTTP status code for blocked entry: 50212-24 01:10:25.679: W/GCM.HTTP(1490): HTTP request blocked due to automatic backoff: https://www.google.com/loc/m/api12-24 01:10:25.710: W/GoogleURLConnFactory(1647): Blocked by temporary_blocked2: https://www.google.com/loc/m/api12-24 01:10:25.710: W/System.err(1647): com.google.android.gms.http.a: Blocked by rule: temporary_blocked2

I googled the above keywords about "Geocoder 502 blocked". No much related results. Nobody talked about the issue on G+ and Twitter at the moment. It's not seeming like usage quota problem as geocoder API does not need an API KEY. It is counting on client's usage. I have no more idea. Hope it resumes normal tomorrow morning when I wake up......
If anyone found it works normal on your device or if you have any idea, let me know pls.....Thx!
