Simplifying what broke Facebook: BGP, DNS and the unified bucket idea

Those 6 hours were probably the longest for Facebook’s engineers and they must felt a lot longer for users including the small and medium businesses that rely heavily on Facebook, WhatsApp, Messenger and Instagram. Facebook’s chief technology officer Mike Schroepfer said in an email to employees after services had been restored, that the issue was “affecting our networking backbone that connects all our data centers together.” It took almost 6 hours for services to make their presence felt online once again. We also have no evidence that user data was compromised as a result of this downtime.” Impact on businesses expected to be huge Facebook doesn’t have any official numbers or data on how many businesses were impacted across Facebook, WhatsApp and Instagram, or the magnitude of losses for small and medium businesses in that outage window. With the outage being global, and across its family of apps, the impact would have been felt by the more than 200 million businesses which use Facebook’s tools around the world.
