This is a problem not just because the site is down, but Facebook’s omnipresent Like button is also completely down, so the entire Internet (or a good percentage of it) is feeling this pain. We’ve reached out to Facebook to see what is up. More to come.
Update: Facebook’s Platform status page gives a little more insight:
Current Status: API Latency Issues We are currently experiencing latency issues with the API, and we are actively investigating. We will provide an update when either the issue is resolved or we have an ETA for resolution.
You’ll also note that they had the same issue yesterday for a few hours — and yes, there were a number of reports yesterday of Facebook’s site being down as well.
