Detect if browser is online
This is a non trivial task, because window.online methods behave differently on Firefox and Chrome.
In addition other browsers do not implement said api at all. Hence the only reliable
way to detect if a browser is online or offline is to query a real life object, which in our case
is a tiny s3 object served through our CDN.
