I honestly don’t know if MSNBC taking the actual online feed overnight.  They would have to schedule commercial breaks so there has to be some proper connectivity, talk back unless it’s remotely triggered. But for NBC News Now is probably just taking the quickest source for news and let it play out.
But for viewers in the UK on satellite wouldn’t they have to convert it back to 50i and then uplink. That could be a delay.

Edit. On my Comcast box I have quick access to move back and forth between NBC News Now and Sky News. They’re treated as an internet channel. There was a 1 second delay from Sky’s channel to NBC News Now.

There's over a minute between them here.

Standards conversion only delays things by a few frames, and it's being uplinked from the same facility as Sky News (Sky Chilworth) so the encoding delay between the two will be comparible. Therefore the delay will be on NBC's end.

The ticker is also noticeable jittering, which Sky's YouTube stream does thanks to YouTube's crude 25 fps to 30 fps conversion, which suggests to me they're taking the feed from YouTube. Or they're getting it to NBC in a very similar way to how they feed the web streams.
