What is BGP, and how might it have helped kick Facebook off the internet?

On Monday, Facebook was completely knocked offline, taking Instagram and WhatsApp (not to mention a few other websites) down with it. Many have been quick to say that the incident had to do with BGP, or Border Gateway Protocol, citing sources from inside Facebook, traffic analysis, and the gut instinct that "it's always DNS or BGP." Facebook is on its way back up, but this all begs the question:

What is BGP?

At a very basic level, BGP is one of the systems that the internet uses to get your traffic to where it needs to go as quickly as possible. Because there are tons of different internet service providers, backbone routers, and servers responsible for your data making it to, say, Facebook, there's a ton of different routes your packets...

Facebook is back online after a massive outage that also took down Instagram, WhatsApp, Messenger, and Oculus

Just as Facebook's Antigone Davis was live on CNBC defending the company over a whistleblower's accusations and its handling of research data suggesting Instagram is harmful to teens, its entire network of services suddenly went offline.

The outage started just before noon ET and took nearly six hours before it was resolved. This is the worst outage for Facebook since a 2019 incident took its site offline for more than 24 hours, as the downtime hit hardest on the small businesses and creators who rely on these services for their income.

Facebook issued an explanation for the outage on Monday evening, saying that it was due to a configuration issue. The company says it doesn't believe any user data was impacted.

After failing all tests...

Facebook has finally given a reason for the six-hour outage Monday

Facebook said in a blog post Monday night that the six-hour outage that took it offline along with Instagram, Messenger, Whatsapp, and OculusVR was the result of a configuration change to its routers — not of a hack or attempt to get at user data. The explanation doesn't give much in the way of detail, but it seems like Facebook's machines weren't able to talk to one another — Facebook says that "this disruption to network traffic had a cascading effect on the way our data centers communicate, bringing our services to a halt."

CEO Mark Zuckerberg posted an apology Monday evening, saying the platforms were coming back online. "Sorry for the disruption today — I know how much you rely on our services to stay connected with the people you...

Twitter, Is It Down, and tons of other sites were struggling due to the Facebook outage

Posted: 04 Oct 2021 05:12 PM PDT

When something like Facebook drops off the internet, there are massive knock-on effects. For example, a website that's meant to tell you if services are down, called Is It Down Right Now, struggled mightily under the load of people trying to see Instagram's status. Cloudflare, a company that runs a DNS service (DNS acts like a map for your web browser when it's trying to find a website and is also the likely culprit when it comes to major outages), reports that it had to mobilize extra resources to keep up with the traffic of people trying to load Facebook (or Instagram or WhatsApp) over and over.

If you need to check if other sites are down, you do still have options. There's the venerable DownDetector, as well as Down for Everyone or...

Losing Facebook is bad, but losing WhatsApp is worse

In the chaos of Monday's Facebook outage, it's easy to lose sight of the company's reach. Not being able to post a new photo to Instagram is an annoyance, but it's not necessarily catastrophic. Yet for WhatsApp users, especially outside of the US, losing Facebook's encrypted messaging service is a life-halting change, and one competing messaging services were eager to capitalize on today.

In February last year, WhatsApp announced it had 2 billion users worldwide. Compare that to original flavor Facebook's 2.5 billion and it's easy to see how many lives WhatsApp touches. It's become the default method to contact people in plenty of countries, including around 400 million unique monthly users in India Bloomberg writes. That goes beyond...

Facebook is coming back after a six-hour outage

Facebook is back online after a six-hour outage due to DNS routing problems. The outage took down Instagram, Whatsapp, Messenger, and Oculus VR as well. For some, those services are back online now; however, after a DNS issue like this, it could take hours for everything to work properly on every network.

The outage started just before noon ET on Monday. It was the most significant outage for Facebook since a 2019 incident took its site offline for more than 24 hours. Journalist Brian Krebs cites a trusted source who told him the incident didn't have any malicious origins. Instead, they said it started with a routine BGP update that went wrong, wiping out the DNS routing...

Locked out and totally down: Facebook’s scramble to fix a massive outage

Posted: 04 Oct 2021 03:34 PM PDT

A prolonged, global outage of Facebook's apps sent the company's engineers scrambling to fix the issue at one of its data centers in California, according to two people familiar with the situation.

The outage, which began around 11:40AM ET on Monday, brought down all of Facebook's apps — including Instagram and WhatsApp — globally, affecting billions of users and millions of advertisers. Inside Facebook, the outage also broke nearly all of the internal systems that employees use to communicate and work. As of 6PM ET, it appears that most of the services are back online.

Several employees told The Verge they resorted to talking through their work-provided Outlook email accounts since Facebook mainly runs on an internal version of the...

Stranger of Paradise Final Fantasy Origin has a new demo, and it’s awesome

Posted: 04 Oct 2021 03:31 PM PDT

Square Enix

Square Enix released Stranger of Paradise Final Fantasy Origin's second demo, showing off a little bit more of what we can expect from the action-oriented Final Fantasy spinoff. The demo gets... interesting. In one cutscene, Jack, the main character, peaced out after a boss fight in hilarious fashion. Players shared the cutscene all over social media with an air of alarmed confusion, but I am here to state for the record that if all of Stranger of Paradise is going to be like that moment, this game is going to kick so much ass.

When Stranger of Paradise Final Fantasy Origin was first announced, fans were a bit surprised since the game is being developed by Team Ninja of Dead or Alive fame. Team Ninja is also behind the Dynasty Warriors-...

The Epic Games Store is getting better achievements next week

Posted: 04 Oct 2021 02:26 PM PDT

The Epic Games Store is taking a bit step towards further competing with more established PC game stores like Steam next week with a proper achievement system (called, of course, "Epic Achievements").

To start, Epic Achievements will only be available on a few games, including Rocket League, Hades, Pillars of Eternity, Kena, Zombie Army 4, and Alan Wake Remastered. Achievements will be broken up into four levels: Bronze (which award 5-45 XP), Silver (50-95 XP), Gold (100-200 XP), and Platinum (which is awarded upon achieving 1000 XP in a game and awards players with an additional 250 XP on their profiles).

Games that are updated to support Epic Achievements will now show those achievements on the game's page in the store,...
