Hi Zweitze,

Looks like that's the Google Web servers detecting a very high traffic from 
your servers and intercepting your calls to prevent a DOS attack. In this 
case, the request doesn't even reach the AdWords API servers, it gets 
intercepted before that. The only workaround is to slow down a bit, and 
retry the call after about 30 seconds.

You might also want to revisit your application's API call strategy to see 
why you'd need so many calls. For instance, is there a chance you could 
group some of the requests into a single request?

Cheers,
Anash P. Oommen,
AdWords API Advisor.
