Since [two days ago][1], I'm experiencing random timeouts to some Api endpoints (Fitness, Drupal). 

You can check this odd behavior using these links:

In case of application timeout, could you check if the Urlfetch is properly reaching the SE end?


I remember to have suffered the same problem [3 months ago][2].
