404 Error while accessing https://www.googleapis.com/oauth2/v1/certs

问题

UPDATE : As of 29.10.204 5:00 PM EST the services seems to be working fine

---

We are trying to do authToken authentication and all the request are failing with 404 error. This started happening since this morning (28-10-2014).

This is happening from Europe (Germany)

Edit

Now I am seeing the same behavior from USA as well but the failure rate is less as compared to Germany.

Same problem here, whats going on with: https://www.googleapis.com/oauth2/v2/certs . It says "Not found". Any information about this? UPDATE: I just refreshed https://www.googleapis.com/oauth2/v2/certs and the certs were there, another refresh they were gone, now they are gone no matter how many times I refresh the page. What's going on? UPDATE 2: I changed my Chrome VPN to Germany and the certs are there for now, but without VPN, from Croatia, they are not, same message: "Not found"

Same issue from Hungary, from DigitalOcean's Amsterdam and New-York region... :/

But, sometimes the reply is 200 and sometimes 404... :(

I've made a workaround! Downloaded the certs, added into my application as static content and rewrite the URL of the public certs. Here is the snippet:

final GoogleIdToken idToken = GoogleIdToken.parse(JSON_FACTORY, token);
final GooglePublicKeysManager manager = new GooglePublicKeysManager.Builder(HTTP_TRANSPORT, JSON_FACTORY)
    .setPublicCertsEncodedUrl("http://localhost:8080/static/certs.json").build();
final GoogleIdTokenVerifier verifier = new GoogleIdTokenVerifier.Builder(manager)
    .setAudience(Arrays.asList(CLIENT_ID)).build();
verifier.verify(idToken);

It's a workaround, I hope, the Google fix the issue... :(
