It could have been a combination of causes, such as a centralized backend system that wasn&#8217;t synchronized properly, a simple mistake in the code, or a lack of coordination between data centers. There are also a few other theories, which may explain the outage. For now, we&#8217;ll stick to the main ones:<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Problems_with_centralized_back-end_systems\"><\/span>Problems with centralized back-end systems<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The company didn&#8217;t give any further details about the outage, which affected all of the Facebook empire&#8217;s apps and sites, but security experts believe the cause was related to misconfigured server computers. The outage reportedly forced Facebook users to disconnect from their accounts and websites, and it cost the world economy about $160 million and more than three billion pesos. Facebook is still investigating the root cause of the outage.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Mistakes_in_softwares_code\"><\/span>Mistakes in software&#8217;s code<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A bug in a software program caused Facebook&#8217;s system to crash, causing a six-hour outage that likely cost the company tens of millions of dollars in lost revenue. The software was supposed to protect Facebook&#8217;s system from accidental shutdowns, but it was malfunctioning when engineers were working on maintaining its global backbone, a network of thousands of miles of fiber-optic cable and dozens of routers.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Simple_mistake\"><\/span>Simple mistake<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Earlier this week, the outage on Facebook affected many people and caused the company to take a long time to repair. The problem was a mix of internal and external systems, all of which were running in the same place, meaning that the company&#8217;s staff was not able to access any of them in order to diagnose the problem. The social networking site&#8217;s door access systems were also offline, preventing employees from physically accessing the data center. The problem was eventually identified and a simple mistake was made &#8211; a mix of DNS and BGP configurations.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Lack_of_coordination_between_data_centers\"><\/span>Lack of coordination between data centers<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A lack of coordination between data centers was one of the reasons behind the Facebook outage. The failure occurred due to configuration changes on backbone routers, causing a cascade of problems. The system relies on the Border Gateway Protocol (BGP), which is like a post office or GPS system that tells the rest of the world where to route traffic. The outage occurred during peak usage times, when Facebook&#8217;s users were most likely using their accounts to access the service.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Mark_Zuckerbergs_personal_wealth_drop\"><\/span>Mark Zuckerberg&#8217;s personal wealth drop<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The recent Facebook crash has drastically cut Zuckerberg&#8217;s personal wealth. He is down $29.7 billion from his original $140 billion net worth. The market cap of Meta Platforms, the company that formerly owned Facebook, dropped nearly 15 percent. The news comes after the company reported fourth-quarter earnings that missed analysts&#8217; expectations. Last quarter&#8217;s figures showed no growth in monthly Facebook users, raising concerns about the company&#8217;s future growth.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Workplace_platform_taken_out\"><\/span>Workplace platform taken out<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>One way to make sure the Workplace platform remains relevant is to keep it focused on India. India has long been one of Facebook&#8217;s most important markets. The low cost of Workplace could make it attractive for Indian operators, who have been trying to expand their reach into the country. And new payment options through WhatsApp could help Facebook gain traction in India. But this new platform isn&#8217;t just about India. It&#8217;s about collaboration, too.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"DNS_servers_removed_from_internets_address_book\"><\/span>DNS servers removed from internet&#8217;s address book<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Symptoms of DNS servers being removed from your internet&#8217;s address book include a message saying your browser can&#8217;t connect to the server. This can happen for many reasons, including DNS errors and other network issues. Run a diagnostic check on your internet connection and try resetting your modem or router. Resetting your modem or router may also clear your cache, so that your device is back in the default setting. If these solutions don&#8217;t work, try changing the DNS server address on your computer.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Why Did Facebook Crash?
