Sky News (UK) is back on air, but they seem to have no astons / chyrons / on screen graphics at all, and I don't think they're able to show prerecorded material either (it's just people in the studio from what I've seen), so presumably they're still having fun issues with their general production systems.
Having another look in, it looks like they're overlaying a static banner along the bottom rather than having a fully working graphics system still (as off 11:30), as that's the only graphics I've seen.
