Some interesting stats over at Pingdom.com, which tracks Twitter.com uptime since March 2009, as well as downtime and average response.
Twitter has seen just 55 minutes of downtime thus far in March, a massive improvement on some of the frightening numbers we saw last year (although most of these can be traced back to one or two very bad days).
The uptime number is pretty impressive, but it’s interesting that the average response has been steadily getting slower since last November’s benchmark. Certainly not enough to notice, but that’s a trend that Biz Stone et al will want to see (at least) flattened. A significant reversal might be an unreasonable expectation given the growth we’ve seen in monthly tweet numbers.
Still, it does give confidence in the system, and makes you realise that Twitter isn’t as down anywhere near as much as it used to be. Although you might think otherwise judging by the number of tweets about it, even if asking ‘Is Twitter down?’ on Twitter is about as surreal as you can get.
