A DoS (denial-of-service) attack more precisely:
Twitter’s site crashed on Thursday at about 3pm BST due to a “denial of service” attack – thousands of remote-controlled virus-infected PCs trying to contact the site.
Though the site came back up after an hour, the company said it was “continuing to defend against and recover from this attack”.
Facebook isn’t operating correctly either. Conspiracy theories time? Stupid kids? North Korea? Putin not liking being mocked by tweet?
Either way as I write (1735 BST) the site isn’t back up, even though Twitter says otherwise…How will we twitterati cope?
