*UPDATE 3* Nothing from Tumblr’s Twitter Account, but the sites appear to be up and stable.
*UPDATE 2* Tumblr’s Twitter Account:
“A faulty network switch is causing severe performance issues. We’re working with our datacenter to get it replaced as quickly as possible.”
*UPDATE* Approximately 40 minutes after going down, Tumblr posted the message below on their sites. In most situations, planned outages or “changes in infrastructure” will be announced and the “Be Back Soon” message would be posted immediately.
Since around 2:15 am Pacific, all blogs hosted on the site went down and as of the time of this post are still down. Their backend user interface and staff blog is also down. There has been no word yet from the company Twitter account.
Tumblr has emerged as a rising star in social media offering more functionality than Twitter, an easier and more convenient posting method than blog platforms such as WordPress, and a community element similar to Vox and Ning. Other social media sites have survived extended downtimes (Twitter is notorious for downtime) but it will be interesting to see if there is any backlash with many active Tumblr users moving the bulk of their online communications and content to their “Tumblelog”.
