cURL error 6: Couldn't resolve host 'www.googleapis.com' on GAE + Pubsub
<p>Good day fellow coders,  </p>

<p>I'm having trouble using PubSub with google-api-php-client on Google App Engine. </p>

<p>Everything used to work perfectly but since this morning I'm having curl errors on the www.googleapis.com host.</p>

<p>Would you have any idea how to solve this ?</p>

<p>Thank you very much for your time !</p>
