Umbhalo obhaliwe ohunyushwe

Kuhunyushwe kusuka ekulandiseni kokuqala kwesiNgisi. Umsindo namazwibela atholakalayo alawulwa yi-YouTube.

I-Facebook isusa ikheli layo

0:00 I-Facebook isusa ikheli layo ku-inthanethi, futhi lapho onjiniyela bayo befika ukuze balibuyisele, abafundi bamabheji nabo abasebenzi, ngoba asebenza nge-Facebook. Uhlaka lwe-Meta olungemuva kwengozi, ngosuku olulandelayo: umyalo ojwayelekile wokulungisa uhlukanisa konke ukuxhumana kwengqalasizinda, futhi ithuluzi elakhelwe ukuvimba imiyalo enjalo linesiphazamiso.

0:16 I-Cloudflare, ngaphandle: ngo-15:40 UTC izindlela eziya kumaseva egama le-Facebook zinyamalala, futhi i-dig facebook.com ibuyisa i-SERVFAIL yonke indawo emhlabeni. Ukuthi kwenzeka kanjani, kungani isici sokuphepha sikwenza kube kubi kakhulu, nokuthi ubani othola icala. Lena yi-The Daily Diff, ngemuva kwengozi. Ntambama kancane, UTC.

Ulayini wesikhathi: 15:39 umyalo → 15:40 ukuhoxiswa → 21:20 ukubuya

0:41 likuphasisile. 15:40. Okuphakelayo kwe-BGP kwe-Cloudflare kugcwele ukuhoxiswa; iziqalo ze-DNS ze-Facebook ziphuma kuthebula lomzila. Ngaphakathi komzuzu onjiniyela be-Cloudflare basegumbini bezibuza ukuthi balimazile yini u-1.1.1.1. 15:45, i-Hacker News, amakhulu amabili namashumi ayisithupha amaphuzu. 16:07, umkhulumeli we-Facebook, ku-Twitter phakathi kwazo zonke izindawo: abanye abantu banenkinga yokufinyelela izinhlelo zethu zokusebenza. Abanye abantu bangabantu abayizigidi eziyizinkulungwane ezintathu nengxenye.

1:06 18:51, i-New York Times: abasebenzi bakhiyelwe ngaphandle kwezakhiwo zabo, amabheji angafa. 19:52, i-CTO iyaxolisa. 21:00, amahora amahlanu edlule, izindlela zibuya; 21:20, i-facebook.com iyaxazulula. Kungani iphutha lengqalasizinda lisusa i-Facebook ku-inthanethi?

Indlela: ukuhlola impilo okukususa, isiphepho se-DNS esingu-30×, izicabha

1:20 Amaseva ayo egama anomthetho: awunakho ukufinyelela ezikhungweni zedatha, zizibeke njengengaphilile, yeka ukukhangisa ikheli lakho. Kuyaqondakala lapho indawo eyodwa ingasebenzi kahle. Lapho yonke ingqalasizinda ihamba, wonke amaseva egama akwenza ngesikhathi esisodwa. Amaseva asebenza. Akekho ongawathola. Isici sokuphepha siguqula iphutha lenethiwekhi libe iphutha lokuba khona. Bese i-inthanethi iyayibhubhisa: izinhlelo zokusebenza ziphinda zizame, abasebenzisi balayisha kabusha,

1:39 futhi isixazululi se-Cloudflare sibona izikhathi ezingamashumi amathathu umthwalo waso ojwayelekile, wendawo engekho. Nezicabha. Amathuluzi, ukufinyelela ngaphandle kwesiteshi, amabheji: inethiwekhi efanayo. Onjiniyela baya ezikhungweni zedatha, abakwazi ukungena, bese behlangana nezintambo eziqinile ezivikela noma ubani onokufinyelela ngokomzimba. Yakhelwe ukubambezela umhlaseli, ibambezela nomnikazi. Ingqalasizinda iyabuya; bakhuphula ithrafikhi kancane, ngamabomu.

1:59 Isikhungo ngasinye sedatha siwele amashumi amamegawathi, futhi ukuhlehlisa lokho ngesinyathelo esisodwa kuwukuphazamiseka kwesibili.

git blame — ukuhlukana

2:05 git blame. I-Facebook, amaphesenti angamashumi amahlanu nanhlanu: umyalo wahlolwa, umhloli waba nesiphazamiso, umyalo owodwa wafinyelela kuwo wonke ama-router. Ukuklama kwe-DNS, amaphesenti angamashumi amabili nanhlanu: ukuhlola impilo okungenayo imiqondo yokulinganisa. Inethiwekhi eyodwa, amaphesenti ayishumi nanhlanu: amathuluzi, ngaphandle kwesiteshi, amabheji. Izintambo, amaphesenti amahlanu, ngokufeza umsebenzi wazo. Umsabalaliso wokuqhumisa: abasebenzisi abayizigidi eziyizinkulungwane ezintathu nengxenye, cishe amahora ayisithupha. Isitoko sivala phansi ngamaphesenti amahlanu, izigidi eziyisithupha ku-Zuckerberg,

Umsabalaliso wokuqhumisa

2:27 ephepheni. I-Telegram ithi abantu abayizigidi ezingamashumi ayisikhombisa babhalisile ngalolo suku. Isinqumo, ngemuva kwengozi: KUDINGEKA UKUHLOLWA. Isitatimende sakusihlwa esifanayo, uhlaka lomlobi oluqanjwe igama ngaphakathi kosuku olulodwa, isiphazamiso sethuluzi lokuhlola esivunywe ngesiNgisi esilula.

Isinqumo + umugqa wangoMsombuluko

2:38 Uhlu lokulungisa: qinisa ukuhlolwa nokuzilolonga. Akukho mayelana nokususa izicabha kunethiwekhi yokukhiqiza. UMsombuluko: beka ukufinyelela kwakho ngaphandle kwesiteshi, nesicabha sakho, kunethiwekhi ongayisebenzisi. operate. Thumela isigameko ongakavunyelwa ukukhuluma ngaso, kumazwana, noma ku-the daily diff dot dev. Futhi yilokho umehluko wanamuhla. Ngingu-Niko wase-Axrisi.

2:58 Hlanganisa ngokuzibopha.
