That page lists this 777 flight as having had an uncontained engine failure, but from photos, video and reporting so far, it's not clear it's uncontained.

Contained failures mean the disintegrating parts don't exit the engine casing, they either remain inside the engine casing or exit out the back. The reporting so far is that all parts exited out the back, not through the engine casing in a way that could have caused catastrophic damage to other parts of the plane.
