Push delivery is operational but might have some slight delay.
Our APIs are operational.

We will continue to monitor the situation.

We have identified a networking issue with our hosting provider (see http://travaux.ovh.net/?do=details&id=46171, http://travaux.ovh.net/?do=details&id=46177 and http://travaux.ovh.net/?do=details&id=46178). They are in the process of implementing a fix.
