Khaladka qaabeynta BGP ayaa sababa in Cloudflare uu shil galo 27 daqiiqo

Shirkadda Cloudflare, bixinta Shabakadda gudbinta nuxurka ee 27 milyan ilaha internetka iyo u adeegida taraafikada 13% ee 1000ka goobood ee ugu waaweyn, daboolid Faahfaahinta dhacdada, taas oo keentay in shaqada qaybo badan oo ka mid ah shabakada Cloudflare ay hakad gasho 27 daqiiqo, oo ay ku jiraan kuwa mas'uulka ka ah gaarsiinta taraafikada London, Chicago, Los Angeles, Washington, Amsterdam, Paris, Moscow iyo St. Petersburg. . Dhibka waxaa sababay isbeddel qaabeyn oo khaldan oo ku yimid router Atlanta. Inta lagu jiro shilka, oo dhacay Juulay 17 laga bilaabo 21:12 ilaa 21:39 (UTC), wadarta mugga taraafikada ee shabakada Cloudflare ayaa hoos u dhacday ku dhawaad ​​50%.

Inta lagu jiro shaqada farsamada, oo doonaya in ay ka saaraan qayb ka mid ah taraafikada mid ka mid ah laf-dhabarka, injineeradu waxay tirtireen hal xariiq oo ku yaal block-ka goobaha kaas oo qeexaya liiska dariiqyada la aqbalay iyada oo loo marayo laf-dhabarka, oo lagu sifeeyo si waafaqsan liiska la cayimay ee horgalayaasha. Waxa ay ahaan lahayd sax in la damiyo blockka oo dhan, laakiin si qalad ah oo kaliya ayaa la tirtiray xariiqda liiska horgalayaasha.

Sababtoo ah ka saarida xiritaanka liiska horgalayaasha, qaybta soo hartay ee xannibaadda ayaa bilaabay in loo qaybiyo dhammaan horgalayaasha iyo router-ku wuxuu bilaabay inuu u diro dhammaan dariiqyada BGP-ga router-yada laf-dhabarrada kale. Isku soo wada duuboo, wadooyinka cusub waxay lahaayeen mudnaan sare (doorbixinta deegaanka 200) marka la barbar dhigo mudnaanta (100) ee loo dejiyay dariiqyada kale ee nidaamka hagaajinta taraafikada. Natiijo ahaan, halkii laga saari lahaa marinka laf-dhabarka, dariiqyada mudnaanta sare leh ee BGP-ga ayaa la daadiyay, taas oo keentay in taraafikada loo diro laf-dhabarka kale loo diro Atlanta, taas oo keentay culeyska router-ka iyo burburka qayb ka mid ah shabakada.

Si looga hortago shilalka la midka ah inay mustaqbalka dhacaan, isbedelo dhowr ah ayaa la qorsheeyay in lagu sameeyo goobaha laf dhabarta ee Cloudflare Isniinta. Xadka tirada ugu badan ee horgalayaasha (ugu badnaan-horgalayaasha) ayaa lagu dari doonaa fadhiyada BGP, kaas oo xannibi doona laf dhabarta dhibta leh haddii horgalayaal aad u badan la dhex maro. Haddii xaddidan lagu dari lahaa mar hore, dhibaatada la isweydiinayo waxay keeni lahayd in la xiro laf dhabarta Atlanta, laakiin ma saameynayso shaqada shabakadda oo dhan, tan iyo shabakadda Cloudflare waxaa loogu talagalay inay u oggolaato laf dhabarta shakhsi ahaaneed inay ku guuldareystaan. Waxaa ka mid ah isbeddelada horay loo qaatay, dib u eegis ku saabsan mudnaanta (doorbida deegaanka) ee waddooyinka maxalliga ah ayaa la xusay, taas oo aan u oggolaan doonin hal router inuu saameyn ku yeesho taraafikada qaybaha kale ee shabakadda.
