The entire BGP layer of the Internet has “constantly updated lists of the possible routes that can be used to deliver every network packet to their final destinations.” It’s a system designed to exchange internet traffic routes that makes the whole internet work, a slightly advanced form of DNS, if you will.
Enter the usual suspect - BGP failureĬloudflare has a very good explanation on this, if you want to geek out a bit more, but for the uninitiated BGP stands for Border Gateway Protocol. However, according to some solid initial reporting by Ars Technica, Facebook’s DNS servers weren’t wholly inaccessible during last night’s epic internet outage - since at least some of them are hosted on Amazon and they were functioning, but billions of requests around the world asking to connect to WhatsApp and Instagram and Facebook couldn’t be fulfilled because of BGP routing failure. Because Facebook is so huge - 2.85 billion monthly active users (separate to Instagram’s 1 billion users and WhatsApp’s 2 billion monthly active users) - it maintains a fairly complex set of DNS servers. Without a working DNS, your computer’s browser or smartphone won’t know where to find Facebook or WhatsApp or Instagram, in effect stopping you from both posting updates and receiving updates from these services. Every website you visit online has its own unique IP address, and the DNS servers are like a postal service that convert to the server record of Facebook’s IP address.ĪLSO READ: From Google To WhatsApp: Worst Server Outages In Recent Internet History Just like any other website, Facebook relies on external DNS servers (Domain Name System servers) for pointing online users to its domain’s IP address - think of it like an actual door number that your postal service has on its record to find and deliver physical mail addressed to you. What caused WhatsApp, Instagram, Facebook internet outage
WHAT CAUSED WHATSAPP OUTAGE OFFLINE
We are all used to the occasional outage suffered by WhatsApp or Instagram or any of these Facebook apps in isolation every now and then, but rarely have we witnessed the whole bouquet of Facebook services remain offline and inaccessible for such an unprecedented period of time. WhatsApp and Instagram, along with Facebook, seemed to have recovered from a historic internet outage that lasted nearly six hours - the longest ever time WhatsApp, Instagram or Facebook’s apps (including Messenger) and services have remained offline, inaccessible to billions of users around the world.
