Pingdom tracked 12 top social networking sites from October 19 to November 19, and found that Microsoft’s Live Spaces had the most downtime, with the site failing to respond for a total of three hours over the course of the month. By contrast, that’s more than Facebook (10 minutes), MySpace (10), Bebo (30), LiveJournal (40) and Orkut (85) combined, and worst on the list.
Number one was Yahoo 360, but that service was so unpopular it’s being closed, so I suspect the zero minutes of downtime can be attributed to zero server load.
