Facebook is down

It returns data, but it's not useful.

For me it's now returning a 500 and an empty body.

Yeah, it does look strange, I was getting a 200 but no data.

Not down in UK.

Posts like this are mostly useless beyond a couple of minutes of their posting, as the issue is often resolved quickly. They might even be irrelevant to you if you are in a different geographic locations. So why bother? There's Twitter for this kind of ephemeral stuff.
