It's 3am: Is Your Social Network Up?

Pingdom.com has a nice chart showing the major social networking sites and their uptime percentages for the first Quarter of 2008. The graph is here.

There has been a lot of talk about Twitter's uptime challenges and this graph does indicate that Twitter is down a lot more than the other networks, yet with a 98.72% uptime it would hardly appear that many users are experiences major problems with Twitter downtimes. It's certainly frustrating to log on expecting something and have no access, but I'd suggest this is hardly the same issue as ISP uptime which is a very reasonable requirement for a robust internet to thrive.

However for some users and businesses that have begun to rely on Twitter as an internal communications tool or for social networking architects like Dave Winer, Twitter downtime has become such a critical issue that a Twitter rebellion appears to be brewing, where the insurgents are suggesting that Twitter's infrastructure is simply not up to the standards that should be required by the community.
