I was up obscenely early this morning, using the Internet, when my Snap UFB connection went down due to "PPPoE timeout". Log below. Does anyone know what causes this type of thing?

I called Snap tech support at 5:35am but "all their operators were on calls" (or perhaps asleep), and after a few minutes I gave up waiting as it came back up.
