This is using the Static Maps API.
I have a web page with 3 img tags, each of which is a call to the static maps API, (NB of course this is not the real api key).
The 3 tags are identical, except the zoom, which is 10, 13 and 16 for the three images.
The API Key is from a project with the Static maps API enabled, and billing configured and enabled.
I have sent perhaps 60 requests in total (this is a brand new development project, so I'm just getting started).
What I'm seeing is that sometimes, all three maps are displayed. At other times one (random from the three) map fails with
403 "The Google Maps API server rejected your request. An internal error was found for this API project."
So if I refresh the page 5 times, ie 15 requests, I get approx 4 failures and 11 successes.
So why is Google Maps randomly rejecting some of the requests with this 403?
