Programeri platforme za zajedni\u010dki rad SourceHut objavili su izvje\u0161taj o incidentu koji je rezultirao prekidom rada usluge tijekom 7 dana zbog dugotrajne DDoS napada na koji infrastruktura projekta nije bila spremna. Osnovne usluge su uspjele biti vra\u0107ene tre\u0107eg dana, ali su neke usluge ostale nedostupne od 10. do 17. sije\u010dnja. U po\u010detnoj fazi napada, programeri nisu uspjeli reagirati i poku\u0161ati se suprotstaviti problemu na svojoj strani servera, jer je sav promet prema serverima SourceHut bio potpuno blokiran na strani vi\u0161eg pru\u017eatelja usluga. <\/p>\n

Za rad SourceHut kori\u0161teni su servere<\/a> u tri data centra. Prvi je imao radnu konfiguraciju, drugi se koristio za rezervnu kopiju, a tre\u0107i je bio namijenjen eksperimentima s migracijom infrastrukture na skalabilniju i otporniju implementaciju usluge (razvijala se verzija SourceHut nove generacije). <\/p>\n

Za rje\u0161avanje pitanja pristupa svojim serverima u glavnom data centru nakon blokade bilo je potrebno oko 9 sati, ali programeri nisu uspjeli ni\u0161ta u\u010diniti jer je ujutro napad poja\u010dan i obuhvatio cijelu podmre\u017eu, nakon \u010dega je pru\u017eatelj ponovno preusmjerio promet na null su\u010delje. Programeri su bili prisiljeni hitno po\u010deti s radom na postavljanju infrastrukture SourceHut u drugom data centru iz rezervnih kopija (privremena podmre\u017ea za pristup glavnim serverima mogla je biti dobivena tek nakon 2 dana). <\/p>\n

Za za\u0161titu od DDoS napada na mre\u017enoj razini, optimalno je bilo smjestiti posredni\u010dki poslu\u017eitelja<\/a> u mre\u017ei oblaka OVH, koji pru\u017ea DDoS za\u0161titu. Svi zahtjevi su upu\u0107eni na ovaj server, a zatim proslije\u0111eni u radnu infrastrukturu. Tijekom migracije nisu se mogle izbje\u0107i gre\u0161ke, koje su oduzele dodatno vrijeme, poput neispravnog vra\u0107anja pomo\u0107u alata rsync, a do\u0161lo je do gre\u0161aka u konfiguraciji mre\u017ee i moglo se rije\u0161iti problema s preusmjeravanjem prometa (prije nego \u0161to je DDoS za\u0161tita u OVH-u po\u010dela djelovati, na radne servere je bio preusmjeren i DDoS promet, na \u0161to je sustav DDoS za\u0161tite reagirao i prepoznao server koji prima zahtjeve kao izvor napada). <\/p>\n

Razvija\u010di su se tako\u0111er obratili Cloudflare-u i nekim drugim servisima za za\u0161titu od DDoS-a, ali je cijena za\u0161tite bila neprihvatljivo visoka. Kasnije su zaposlenici Cloudflare-a uspjeli dogovoriti s upravom pru\u017eanje za\u0161tite projektu SourceHut besplatno kao sponzorsku pomo\u0107, no razvija\u010di SourceHut-a su odbili ovu ponudu jer su do tog trenutka ve\u0107 zna\u010dajno napredovali u rje\u0161avanju problema vlastitim snagama. <\/p>\n

Implementacija nove infrastrukture SourceHut i premje\u0161taj projekta na servere u drugom data centru planirana je postupno tijekom najmanje jedne godine, ali su, u trenutnim okolnostima, migraciju morali izvr\u0161iti hitno u roku od 7 dana. Trenutno su svi servisi SourceHut premje\u0161teni u drugi data centar i rad platforme je potpuno obnovljen. <\/p>\n

Platforma SourceHut se razlikuje po jedinstvenom korisni\u010dkom su\u010delju, koje nije sli\u010dno GitHub-u i GitLab-u, ali je jednostavno, vrlo brzo i radi bez JavaScripta. SourceHut pru\u017ea mogu\u0107nosti kao \u0161to su rad s javnim i privatnim Git i Mercurial repozitorijima, fleksibilan sustav upravljanja pristupom, wiki, primanje izvje\u0161taja o gre\u0161kama, ugra\u0111enu infrastrukturu za kontinuiranu integraciju, chat, rasprave putem emaila, hijerarhijski pregled arhiva mailing lista, pregled promjena putem weba, dodavanje bilje\u0161ki u kod (prikazivanje linkova i dokumentacije). Kada su aktivirane odgovaraju\u0107e postavke, omogu\u0107ena je sudjelovanje u razvoju korisnicima bez lokalnih ra\u010duna (autentifikacija putem OAuth-a ili sudjelovanje putem emaila). Kod je napisan na jezicima Python i Go, i distribuira se pod licencom GPLv3.
