Tumblr Had 42 Hours of Downtime in 2011 — And That’s an Improvement
Tumblr, the fast-growing blogging social network, goes down a lot. How much? It had 42 hours of downtime in 2011, by far the most among major blogging hosts, according to Pingdom.
However, that’s a significant improvement from 2010. Tumblr had more downtime in two months in 2010 than in the first 11 months of 2011, Pingdom said. This year the longest Tumblr outage was three hours, compared to almost 24 hours last year.
Meanwhile, Pingdom’s measurements found that Blogger was by far the most reliable blog host. It had uptime of 99.998 percent in 2011, which Pingdom gushed was “highly impressive” and way better than might be expected for such a large Web site.
That strikes me as off, given that Blogger had an outage of more than 20 hours in May, which it attributed to data corruption. I’ve asked Pingdom for clarification.
Pingdom said TypePad and WordPress also had more than 99.9 percent uptime this year, while Posterous was just under that.
