Those figures are a combination of downtime across all regions globally. So it doesn't mean that any individual servers were down. The largest downtime was in Europe, with had 5.97 hours last year.

Factors for downtime were an update bug in November and weather. The bug is very unlikely to happen again. Outages due to weather really don't tell you much at all other than that they were unlucky. Overall, I would say the downtime numbers are not very useful.
