MySpace has had better uptime than Facebook thus far in 2008, as MySpace has been offline for just 25 minutes, compared to 1 hour and 35 minutes for Facebook. But Yahoo!360 and LiveJournal have them both beat, according to a rating of uptime on social networks that has just been published by Pingdom. The monitoring found at least one instance in which a sopcial network's effort to transition to an application platform may be affecting performance:
Bebo's downtime has increased significantly lately and has had by far the most downtime of the 14 social networks we monitored for this survey. More than 12 hours of downtime in less than two months is a lot, and it could possibly be caused by the new open application platform that Bebo launched in December, allowing third-party developers access to its platform, Facebook style. It could be putting more strain on Bebo's systems than they anticipated.
LinkedIn, which is widely used among business professionals, has had 4 hours of downtime in 2008. How does your favorite network fare? Check out the results of Pingdom's research.
