Twitter’s fail whale is back in action, which means the must have Internet service for chattering classes is down for the count. A company spokesperson said that the service has suffered an outage and won’t be back before 3 am PST. “We’re currently experiencing site availability issues resulting from a failed enhancement of the site,” the spokesperson wrote in an email. “Our infrastructure and operations engineers are currently working to resolve this.” For further updates, you can check out the Twitter status blog.
