Twitter Be Down, Be Down The Most

Website monitoring company Pingdom is out with their downtime study for the top social networks for the first four months of 2008. Guess who leads with the most downtime? If you guessed Twitter, you win the prize! Pingdom reports that Twitter has been down over 37 hours in the past four months. Coming up right behind Twitter is the service that wants to go to Prom but has no date, Pownce. Pownce claims an exciting 13+ hours of downtime.

Big player networks MySpace and Facebook came in with 1 and 2 hours of downtime respectively. Now this makes sense, Twitter and Pownce are new and while it seems to the 250 that Twitter has been around forever, they haven't. Part of their downtime is caused by maintenance and upgrades. Larger networks such as MySpace and Facebook have huge valuations which allow them to have the server capacity and production environments that don't require downtime for changes.

Below is the downtime chart and also check Pingdom's analysis.
