During the recent outage of the main data center of hoster Rackspace the company used Twitter to communicate information about the outage to the outside world.
Also our paessler.com website was affected by the downtime and since we could not even reach the Rackspace’s websites we turned to Twitter for up-to-the-minute information. And so did others, too. See:
