Facebook, Instagram, WhatsApp bloccati in tutto il mondo per sei ore
Facebook e le sue proprietà (WhatsApp, Instagram e Oculus) sono completamente inaccessibili da alcune ore in tutto il pianeta. Facebook ha confermato laconicamente il problema con un post su Twitter.
Anche la pagina ufficiale di stato di Facebook, status.fb.com, è inaccessibile.
Questa è una mia prima sintesi della situazione. La aggiornerò man mano che ci saranno novità.

Ultimo aggiornamento: 2021/10/04 23:50 (sei ore dall’inizio del collasso).
A quanto risulta dalle prime analisi e indiscrezioni, tutto è iniziato intorno alle 15.40 UTC (le 17.40 italiane) in seguito a un errore commesso durante un cambiamento di configurazione interno a Facebook.
Questo errore comporta che tutta Internet non sa più dove trovare Facebook, perché qualcuno di Facebook ha cancellato la mappa che dice dove si trova Facebook e che strada fare per raggiungerlo.
In termini leggermente tecnici: l’errore di configurazione ha reso inaccessibili da remoto i BGP peering router di Facebook, i computer dell’azienda che gestiscono il BGP (Border Gateway Protocol), che è il protocollo di Internet che determina l’instradamento (routing) dei dati da trasmettere, come spiegato qui e qui.
Between 15:50 UTC and 15:52 UTC Facebook and related properties disappeared from the Internet in a flurry of BGP updates. This is what it looked like to @Cloudflare. pic.twitter.com/PFw5FR2W5j

ThousandEyes tests can confirm that at 15:40 UTC on October 4, the Facebook application became unreachable due to DNS failure. Facebook’s authoritative DNS nameservers became unreachable at that time. The issue is still ongoing as of 17:02 UTC. pic.twitter.com/zNmZWTxEUo

L’errore ha causato l’eliminazione improvvisa dei route (percorsi) BGP che consentivano di accedere ai server DNS di Facebook, per cui il DNS di Facebook non va più(lo sappiamo da tweet come questo).
Il problema è che correggere questo errore richiede che si acceda fisicamente a questi peering router, visto che non sono più raggiungibili da remoto, ma chi può farlo non è necessariamente dotato delle autorizzazioni e dell’autenticazione che sono necessari. BNO News alle 22.15 ha tweetato, citando il NYT, che Facebook ha inviato una squadra a uno dei suoi data center a Santa Clara, in California, per resettare manualmente i server.
Non solo: questo errore implica che non funziona più nessuno dei servizi interni di Facebook (mail, strumenti di gestione, sistemi di sicurezza, agende, la messaggistica interna Workplace, eccetera), visto che sono tutti sul dominio Facebook.com, che è totalmente irraggiungibile, per cui neppure i dipendenti dell’azienda possono usarli per comunicare tra loro, come nota il New York Times.
E non è finita: se, come sembra (anche da qui), le serrature delle porte degli uffici di Facebook sono “smart” (basate sull’IoT), dipendono dalla connessione a Internet e dall’accesso ai server di Facebook. Che sono inaccessibili, per cui molti dipendenti non riescono a entrare perché i loro badge non funzionano. Il New York Times conferma.
Non ci sono indicazioni di eventuali attacchi esterni: tutto indica un errore interno di dimensioni catastrofiche.
NOTA: L’annuncio della diffusione dei dati di circa un miliardo e mezzo di utenti Facebook non è correlato a questo incidente. I dati non includono password.
Questo errore sta avendo conseguenze a catena sul resto di Internet, e arrivano segnalazioni di rallentamenti anche per Disney+, Netflix e Twitter (che finora ha retto):

Finché Facebook è fuori uso, è possibile che non funzionino neanche gli accessi alle app o ai siti che usano l’opzione “Login tramite Facebook” (per esempio Pokémon Go).
In pratica, un miliardo di smartphone e di altri dispositivi sta cercando disperatamente di trovare Facebook e questi tentativi inutili generano traffico DNS che rallenta tutti gli altri accessi.
Agli utenti di Facebook, Instagram, WhatsApp e Oculus non resta che aspettare che la situazione venga ripristinata ed eventualmente installare app analoghe come Signal o Telegram. Aggiungo un paio di suggerimenti:
- Disattivate le notifiche di Facebook, WhatsApp e Instagram, altrimenti quando torneranno a funzionare verrete sommersi da un fiume di notifiche rimaste in coda (grazie ad @alessLongo per la dritta).
- NON FIDATEVI di eventuali messaggi o mail che invitano a cliccare da qualche parte per riattivare i vostri account. I truffatori approfitteranno sicuramente del panico causato da questo collasso e invieranno messaggi-esca che porteranno a siti-trappola che somigliano alle schermate di login dei social di Zuckerberg ma sono in realtà delle copie che rubano le password.

A shoppable TV screen with YouTube
Whether kicking back with a movie or kicking their fitness routine into gear, more people are choosing to experience YouTube on the big screen. When they do, they can watch longer, enjoy multiple shows back to back, and experience it all from the comfort of their couch with friends and family. Many even build a routine around it. In the U.S., over 120 million people streamed YouTube or YouTube TV on their TV screens in December 2020.1
To help consumers more easily learn about the products and services they’re interested in, we’re making YouTube ads on connected TVs more shoppable. Today, we’re expanding Video action campaigns to CTVs to help advertisers drive more online sales or generate leads, and grow their business.
With a quarter of logged-in YouTube CTV viewers watching primarily on TVs,2 the living room is becoming an essential place for brands to drive incremental conversions with new audiences. In early experiments for Video action campaigns on TV screens, over 90% of conversions coming from CTV would not have been reachable on mobile and desktop devices.3
Drive online sales and leads on the TV screen with Video action campaigns
If your goal is to drive online sales or generate leads, we recommend using Video action campaigns. Video action campaigns make it easy to find new customers efficiently in a single campaign by combining inventory from across YouTube and Google video partners — and now YouTube CTV. For the first time, performance advertisers can take advantage of YouTube on CTV to drive and measure conversions.
When a viewer sees a Video action campaign on their TV, they are invited through a URL at the bottom of their screen to continue shopping on the brand’s website from their desktop or mobile device — without interrupting their viewing session.
Advertisers can also take advantage of the Conversion Lift beta on TV screens to get actionable results in real time. Conversion Lift measures the impact of YouTube ads on driving user actions, such as website visits, sign ups, purchases and other types of conversions.
Video action campaigns on TV screens are now globally available through Google Ads. Reach out to your Google team or visit the Help Center to learn more.
