Major social media services including WhatsApp Facebook and Instagram broke down by a massive outage impacting potentially hundreds of millions of users. There were more than 20,000 incidents of people reporting issues with Facebook and Instagram. Users trying to access Facebook in affected areas were greeted with the message: “Something went wrong. We’re working on it and we’ll get it fixed as soon as we can.” One Facebook employee added that all internal tools were down. Facebook’s response was made much more difficult because employees lost access to some of their own tools in the shutdown. Facebook had experienced similar widespread outages with its suite of apps this year in March and July. 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. WhatsApp Facebook and Instagram broke down cause of the outage remains unclear. It appears that Facebook withdrew authoritative DNS routes that let the rest of the internet communicate with its properties. Such routes are part of the internet’s Domain Name System, a key structure that determines where internet traffic needs to go. If Facebook’s DNS records disappeared, apps and web addresses would be unable to locate it.
