Facebook issued a statement about the outage, saying that their engineers had “identified the cause of the outage and recovered the site quickly.” “You should now see decreasing error rates while our systems stabilize. We don't expect any other break in service. I'll post another update within 30 mins. Thank you for your patience,” the statement said. A Facebook spokesman, however, denied that the outage was caused by a hack. "This was not the result of a third party attack but instead occurred after we introduced a change that affected our configuration systems. We moved quickly to fix the problem, and both services are back to 100 percent for everyone," the company said in a statement emailed to CNBC.
