Uye S3 inogona kudonha - zvakaitika kamwe chete. Nokudaro, takasvika kune chirongwa chinotevera: makore mashomanana apfuura kwakanga kusina nzvimbo dzakakomba dzekuchengetera zvinhu zvevanhu muRussia, uye takafunga nezvechisarudzo chekuita chimwe chinhu chedu ...

Ah, uye Amazon yakatiza ...
Kubvumbi ino inocherekedza zuva rekutanga kweTeregiramu ichivharira muRussia. Mupi akanyanya kubatwa akawira pasi peizvi iAmazon. Uye, zvinosuruvarisa, makambani eRussia aishandira nyika yose akatambura zvakanyanya.
Kana iyo kambani iri yepasirese uye Russia idiki diki chikamu chayo, 3-5% - zvakanaka, imwe nzira kana imwe, unogona kuvabayira.
Kana iyi iri kambani yeRussia chaiyo - ndine chokwadi chekuti inoda kuwanikwa munharaunda - zvakanaka, inongove yakanakira vashandisi pachavo, yakagadzikana, uye pachave nenjodzi shoma.
Ko kana iyi iri kambani inoshanda pasi rose uye iine huwandu hwakaenzana hwevatengi vanobva kuRussia uye kumwe kutenderera pasirese? Kubatana kwezvikamu kwakakosha, uye ivo vanofanirwa kushanda pamwe neimwe nzira kana imwe.
Pakupera kwaMarch 2018, Roskomnadzor yakatumira tsamba kune vashandi vakakura zvikuru vachitaura kuti vakaronga kuvhara mamiriyoni akawanda eAmazon IPs kuitira kuvhara ... Zello messenger. Kutenda kune avo vanopa - vakabudirira kuburitsa tsamba kune wese munhu, uye pakave nekunzwisisa kuti kubatana neAmazon kunogona kuparara. Wakanga uri Chishanu, takamhanya tichitya kune vatinoshanda navo kubva servers.ru, tichiti: "Shamwari, isu tinoda maseva akati wandei achange ari muRussia, kwete muAmazon, asi, semuenzaniso, kumwe kuAmsterdam," kuitira kuitira kuti tikwanise kuisa isu pachedu VPN uye proxy ipapo kune mamwe magumo atisingakwanise kupesvedzera neimwe nzira, semuenzaniso endponts yeiyo s3 - hatingaedze kusimudza sevhisi nyowani uye kuwana yakasiyana ip, isu tichiri kuda kuti usvike ikoko. Mumazuva mashoma, isu takamisa maseva aya, tikaasimudza nekumhanya, uye, kazhinji, takagadzirira nguva iyo kuvharika kwakatanga. Zvinoda kuziva kuti RKN, achitarisa kupokana uye kutya, akati: "Aiwa, isu hatichavharidzi chero chinhu izvozvi." (Asi izvi ndizvo chaizvo kusvikira panguva iyo Teregiramu yakatanga kuvharwa.) Mushure mekugadzirisa maitiro ekudarika uye nekuona kuti kuvhara kwakanga kusina kuiswa, isu, zvisinei, hatina kutanga kugadzirisa nyaya yacho yose. Hongu, kana zvakadaro.
Uye muna 2019, isu tichiri kurarama mumamiriro ekuvharira. Ndakatarisa manheru manheru: inenge mamiriyoni IPs inoramba ichivharwa. Ichokwadi, Amazon yakanga inenge isina kuvharwa zvachose, pakukwirira kwayo yakasvika mamiriyoni makumi maviri emakero ... Kazhinji, chokwadi ndechokuti panogona kunge pasina kuwirirana, kuwirirana kwakanaka. Pakarepo. Inogona kunge isipo nekuda kwezvikonzero zvehunyanzvi - moto, vanochera, zvese izvo. Kana, sezvataona, kwete zvachose tekinoroji. Naizvozvo, mumwe munhu muhombe uye muhombe, ane maAS avo, anogona kubata izvi nedzimwe nzira - kubatanidza zvakananga uye zvimwe zvinhu zvatova padanho re20. Asi mune yakapfava vhezheni, seyedu kana kunyange idiki, iwe unogona, kana zvikaitika, uine redundancy padanho remaseva akasimudzwa kumwewo, akagadzirirwa pamberi vpn, proxy, nekugona kukurumidza kushandura iyo kumisikidzwa kwavari muzvikamu izvozvo. izvo zvakakosha pakubatana kwako. Izvi zvakauya zvakatinakira kanopfuura kamwe, pakatanga kuvharika kweAmazon; mune yakaipisisa mamiriro, isu takangobvumira S2 traffic kuburikidza navo, asi zvishoma nezvishoma zvese izvi zvakagadziriswa.
Nzira yekuchengetedza ... mupi wese?
Parizvino isu hatina mamiriro ekuti kana iyo Amazon yese yadzika. Tine mamiriro akafanana kuRussia. MuRussia, takagamuchirwa nemumwe mupi, kubva kwatakasarudza kuva nemasaiti akati wandei. Uye gore rapfuura takatarisana nedambudziko: kunyangwe idzi dziri mbiri nzvimbo dzedata, panogona kunge paine matambudziko atove padanho remupi wetiweki gadziriso izvo zvicharamba zvichikanganisa ese ari maviri data data. Uye tinogona kupedzisira tisingawanikwe pane ese mawebhusaiti. Chokwadi ndozvakaitika. Takapedzisira taongororazve mavakirwo emukati. Izvo hazvina kuchinja zvakanyanya, asi kuRussia isu tava nemasaiti maviri, ayo asiri kubva kumupi mumwe chete, asi kubva kune maviri akasiyana. Kana imwe ikakundikana, tinogona kuchinjira kune imwe.
Hypothetically, yeAmazon isu tiri kufunga nezve mukana wekuchengetera pamwero wemumwe mupi; zvichida Google, zvichida mumwe munhu ... Asi kusvika ikozvino takacherechedza mukuita kuti nepo Amazon iine tsaona pamwero weimwe nzvimbo inowanikwa, tsaona pamwero wedunhu rose hazviwanzo. Naizvozvo, isu tine pfungwa yekuti isu tinogona kugadzira "Amazon haisi Amazon" yekuchengetera, asi mukuita izvi hazvisati zvaitika.
