![]() ![]() If that failed, it could be in for “a world of hurt” - because it would need to order manual changes at outside data centres, he added. Colombia University computer scientist Steven Bellovin tweeted that he expected Facebook would first try an automated recovery in such a case. “No one else announced these routes,” said Madory.Ĭomputer scientists speculated that a bug introduced by a configuration change in Facebook’s routing management system could be to blame. ![]() Madory said there was no sign that anyone but Facebook was responsible and discounted the possibility that another major internet player, such as a telecom company, might have inadvertently rewritten major routing tables that affect Facebook. Jake Williams, chief technical officer of the cybersecurity firm BreachQuest, said that while foul play cannot be completely ruled out, chances were good that the outage is “an operational issue” caused by human error. “They’re more susceptible to social engineering because they’re so desperate to communicate.” Tobac said during previous outages, some people have received emails promising to restore their social media account by clicking on a malicious link that can expose their personal data. “They don’t know how to contact the people in their lives without it,” she said. So many people are reliant on Facebook, WhatsApp or Instagram as a primary mode of communication that losing access for so long can make them vulnerable to criminals taking advantage of the outage, said Rachel Tobac, a hacker and CEO of SocialProof Security. Without Facebook broadcasting its routes on the public internet, apps and web addresses simple could not locate it. Such routes are part of the internet’s Domain Name System, a central component of the internet that directs its traffic. Madory said it appears Facebook withdrew “authoritative DNS routes” that let the rest of the internet communicate with its properties. ![]() Facebook’s request on Monday that a revised antitrust complaint against it by the Federal Trade Commission be dismissed because it faces vigorous competition from other services seemed to ring a bit hollow. ![]()
