2021 Facebook Outage
On October 4, 2021, at 15:39 UTC, the social network Facebook and its subsidiaries, Messenger, Instagram, WhatsApp, Mapillary, and Oculus, became globally unavailable for a period of six to seven hours. The outage also prevented anyone trying to use " Log in with Facebook" from accessing third-party sites. During the outage, many users flocked to Twitter, Discord, Signal, and Telegram, resulting in disruptions on these sites' servers. The outage was caused by the loss of IP routes to the Facebook Domain Name System (DNS) servers, which were all self-hosted at the time. Border Gateway Protocol (BGP) routing was restored for the affected prefixes at about 21:50, and DNS services began to be available again at 22:05 UTC, with application-layer services gradually restored to Facebook, Instagram, and WhatsApp over the following hour, with service generally restored for users by 22:50. Causes Security experts identified the problem as a Border Gateway Protocol (BGP) withdrawal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Router (computing)
A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions between networks and on the global Internet. Data sent through a network, such as a web page or email, is in the form of data packets. A packet is typically forwarded from one router to another router through the networks that constitute an internetwork (e.g. the Internet) until it reaches its destination node. A router is connected to two or more data lines from different IP networks. When a data packet comes in on one of the lines, the router reads the network address information in the packet header to determine the ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey. The most familiar type of IP routers are home and small office routers that simply forward IP packets between the home computers and the Internet. More sophisticated routers, ...
