About 6 days ago we have noticed, that there is an issue with some of our Feature Services hosted on ArcGIS Online.
What's happening is that roughly every tenth request to the service returns a 503 error (service unavailable).

Here are two of the services affected:

They are not publicly accessible, but our Flex apps use them through App logins (

The problem can by reproduced by simply refreshing the service page several times using CTRL + F5 until it throws an error.

We've made sure that the problem isn't only for our Network. In fact I've tested the service from remote servers based in different countries (including US).

Our applications that use those layers, can't load 1/10th of them, 1/10th of queries fail and our app users don't like all of those error messages :/. We would be glad if anyone here could look into this issue.
