'Explained' may be a bit of an overstatement for that page. 'Acknowledged and provided timestamps' is more like it.

EDIT: Although it does look like they will update it with more information soon.

Interesting that the status page marks this as a 'service disruption' versus 'service outage'. The page doesn't have any definitions of these terms anyway, so it's hard to know what the difference is.

I was completely unable to access the service. It seems like a 'service outage' to me!
