ADD: add a fallback site for internet detection

[koying]

Somehow, google might be blocked ("Great Wall", firewall, proxy).
Little chance anyone would care to block w3c ;)

Seem legit but i wonder if we should use an internal (kodi) site first.

[koying]

Any non-contentious, 99.9% up, site really.
Kodi, being categorized as "entertainment" might be blocked in, e.g., office environments

[mkortstiege]

Oh, right. w3c sounds like a good choice then.

I think you should use time.windows.com. It's what MS Windows uses around the world, so there is, by extension, an element of reliability.

Another problem with using Google, or sites that have geo-location based redirect, is Kodi does not handle the redirect properly. Example: try http://google.com and it will report 'not connected' in the UK, because it is not handling the direct to http://google.co.uk properly. If you use http://google.co.uk explicitly, it's fine.

Well, time.window.com is their ntp server, isn't it? We do a simple http get on 80 for this.
It happens that there is a landing http page, there, but I'm not sure we can assume it's anywhere reliable...

[samnazarko]

Wrong URL, my bad,

http://www.msftncsi.com/ncsi.txt is what OSMC uses (and Windows clients too)

[koying]

Makes sense. This is the site MS tries to reach to check Windows internet connectivity.

@koying mind updating so we can merge this one?

[koying]

Done. I've made the MS one primary, and kept W3C as secondary.

Thanks. jenkins build this plase.
