Fire an event when push server connectivity changes

[ghost]

Do we want a way to notify sites when the connection to the push server is interrupted or resumed? Firefox Hello originally requested this as a way to show a user's presence status for IM and calls.

This would be similar to navigator.onLine and the online/offline events...though accounting for cases where the browser is online, but can't receive pushes because the server is down or blocked by a proxy.

I think this came up once before, but I can't find the issue.

No. The expected behaviour for push is that devices will go offline, and often. We don't want to wake the device specially every time this happens.

I know that some people like presence, but the whole point of having a mobile device with a push service is to render presence redundant. With these, it is always possible to send a message to a user.

Presence is then reduced to whether the user wants to be disturbed, a far more valuable signal, albeit a harder one to reliably acquire.

As for the case where the push service is down when the network isn't, maybe we can let the user know, but that becomes a UX problem.

All good points!
