Kaasaegsed andmekeskused on usaldusv\u00e4\u00e4rsed, kuid igasugune varustus rikneb aeg-ajalt. Me oleme koostanud v\u00e4ikese m\u00e4rkme, kus toome v\u00e4lja k\u00f5ige olulisemad juhtumid aastast 2018.<\/em><\/p>\n

\n\"Suured<\/a><\/noindex><\/p>\n

Digitootmise m\u00f5ju majandusele kasvab, t\u00f6\u00f6tletava teabe hulk suureneb, uusi objekte ehitatakse ja see on hea, kuni k\u00f5ik t\u00f6\u00f6tab. Kahjuks kasvab ka andmekeskuste riketest tulenev m\u00f5ju majandusele, alates hetkest, kui inimesed hakkasid neisse asutama kriitilist \u00e4ri IT-infrastruktuuri \u2013 see on digitaaliseerimise v\u00e4ltimatu tagaj\u00e4rg. Avaldame v\u00e4ikese valiku k\u00f5ige silmapaistvamatest \u00f5nnetustest, mis juhtusid erinevates riikides m\u00f6\u00f6dunud aastal.<\/p>\n

Ameerikas<\/h2>\n

<\/p>\n

See riik on tunnustatud liider andmekeskuste \u00fclesehitamise valdkonnas. Ameerika \u00dchendriikides on k\u00f5ige rohkem suuri kommertsi- ja ettev\u00f5tte andmekeskuste riketest<\/a>, mis teenindavad globaalseid teenuseid, mist\u00f5ttu on seal aset leidnud \u00f5nnetuste tagaj\u00e4rjed k\u00f5ige ulatuslikumad. M\u00e4rtsi alguses tabas v\u00f5imas ts\u00fcklon nelja Equinixi operaatori objekti, mis kogesid elektrivarustuse s\u00fcsteemi riket. Ala kasutati Amazon Web Services (AWS) seadmete jaoks, \u00f5nnetus p\u00f5hjustas paljude populaarsete teenuste k\u00e4ttesaamatuse: kannatada said GitHub, MongoDB, NewVoiceMedia, Slack, Zillow, Atlassian, Twilio ja Capital One, samuti virtuaalne assistent Amazon Alexa. <\/p>\n

<\/p>\n

Septembris tabasid ilmastikun\u00e4htused Texase osariigis asuvaid Microsofti andmekeskusi, mil ajal murdis \u00e4ike terve piirkonna elektrivarustuse t\u00f6\u00f6. \u00dches andmekeskuses, mis l\u00e4ks \u00fcle diiselgeneratori toitele, lakkas jahutus t\u00f6\u00f6tamast teadmata p\u00f5hjusel. \u00d5nnetuse tagaj\u00e4rgede likvideerimiseks kulus mitu p\u00e4eva, ja kuigi koormuse tasakaalustamise t\u00f5ttu ei olnud see rike kriitiline, m\u00e4rkasid Microsofti pilveteenuste kasutajad \u00fcle kogu maailma teenuste aeglustumist.<\/p>\n

<\/p>\n

<\/p>\n

K\u00f5ige t\u00f5sisem \u00f5nnetus juhtus 20. augustil \u00fches Rostelecomi andmekeskuses. Selle t\u00f5ttu seiskusid \u00dchise Riigi Kinnisvara Register serverid 66 tunniks, mist\u00f5ttu tuli need viia reservplatsile. Rosreestr suutis 3. septembril taastada k\u00f5igilt kanalitelt esitatud taotluste t\u00f6\u00f6tlemise \u2013 riigiasutus p\u00fc\u00fcab Rostelecomilt sisse n\u00f5uda suuri summasid teenuse taseme kokkuleppe rikkumise eest. <\/p>\n

<\/p>\n

16. veebruaril, seoses Lenenergo v\u00f5rgu probleemidega, k\u00e4ivitati Xelneti (Peterburi) andmekeskuses varus\u00fcsteemi. L\u00fchiajaline katkestus toiteallikas p\u00f5hjustas mitmete teenuste t\u00f6\u00f6s probleeme: eriti kannatas suur pilveteenuste pakkuja 1cloud, kuid Venemaa internetikasutajatele oli k\u00f5ige h\u00e4irivam probleem sotsiaalv\u00f5rgustikku \u201eVKontakte\u201c sisenemise v\u00f5imatuse t\u00f5ttu. Huvi pakkus, et l\u00fchiajalise elektrikatkestuse tagaj\u00e4rgede t\u00e4ielik likvideerimine v\u00f5ttis aega umbes 12 tundi.<\/p>\n

<\/p>\n

Euroopa Liit<\/h2>\n

<\/p>\n

EL-is registreeriti 2018. aastal mitmeid t\u00f5siseid intsidente. M\u00e4rtsis toimus KLM-i lennufirma andmekeskuses viga: elektritoide lakkas 10 minutiks ning diiselgeneraatorite v\u00f5imsus osutus seadmete t\u00f6\u00f6ks ebapiisavaks. Osa serverid<\/a> katkestati ning lennufirmad pidid t\u00fchistama v\u00f5i edasi l\u00fckkama mitu k\u00fcmnet lendu. <\/p>\n

<\/p>\n

See ei olnud ainus lennutransportidega seotud juhtum \u2013 juba aprillis toimus Eurocontroli andmekeskuses elektrikatkestus. See organisatsioon haldab lennuliiklust Euroopa Liidus ning seni, kuni spetsialistid likvideerisid 5 tundi kesta valmistusi, pidid reisijad taas taluma hilinemisi ja lende edasi l\u00fckkama. <\/p>\n

<\/p>\n

Andmekeskustes, mis teenindavad rahasektorit, tekivad v\u00e4ga t\u00f5sised probleemid. Siin on katkestuste hind tavaliselt k\u00f5rge ning objekti usaldusv\u00e4\u00e4rsus on vastav, kuid intsidentide vastu see ei kaitse. 18. aprillil ei saanud Nordic NASDAQ b\u00f6rs (Helsingi, Soome) kauplemist kogu P\u00f5hja-Euroopas p\u00e4evaks alustada, kuna kommertskeskkonna andmekeskuses DigiPlex oli sundkatkestatud, p\u00e4rast volitamata tulekustutuss\u00fcsteemi aktiveerimist. <\/p>\n

<\/p>\n

7. juunil p\u00f5hjustasid andmekeskuse katkestused Londoni b\u00f6rsi (London Stock Exchange, LSE) kauplemise alustamise tunni v\u00f5rra edasi l\u00fckkamist. Lisaks katkestati juunis Euroopas p\u00e4evaks rahvusvahelise makses\u00fcsteemi VISA teenused, kuigi juhtumi detaile ei avaldatud.<\/p>\n

<\/p>\n

Jaapan<\/h2>\n

<\/p>\n

Suvel 2018 toimus Tokyos, Amazonas ehitatava andmekeskuse maapinnast allpool asuvates tasandites tulekahju, milles hukkus 5 t\u00f6\u00f6tajat ja sai vigastada v\u00e4hemalt 50 inimest. Tulekahju kahjustas umbes 5000 m2 hoone ruume. Uurimine n\u00e4itas, et tulekahju p\u00f5hjustas inimfaktor: ettevaatusabin\u00f5ude mittet\u00e4itmine atset\u00fcleenip\u00f5lemisvahenditega l\u00f5hkus isolatsiooni.<\/p>\n

<\/p>\n

Rikkumise p\u00f5hjused<\/h2>\n

<\/p>\n

Esitatud nimekiri juhtumitest ei ole kaugeltki t\u00e4ielik, kuna andmekeskuste avariide t\u00f5ttu kannatavad panganduse ja telekommunikatsiooni operaatorite kliendid, pilveteenuste teenused l\u00e4hevad offline ja h\u00e4daabit\u00f6\u00f6tajate t\u00f6\u00f6 on samuti h\u00e4iritud. V\u00e4ike teenuse katkemine v\u00f5ib p\u00f5hjustada suuri kahjusid, samas kui Uptime Institute'i andmete kohaselt on enamus (39%) rikete p\u00f5hjuseid seotud elektrivarustus s\u00fcsteemiga. Teisel kohal (24%) on inimfaktor ning kolmandal (15%) konditsioneerimise s\u00fcsteem. Loomulikest n\u00e4htustest tulenevaid avariisid on vaid 12%, neist 10% toimuvad muudel p\u00f5hjustel kui loetletud. <\/p>\n

<\/p>\n

Hoolimata rangetest usaldusv\u00e4\u00e4rsuse ja turvalisuse standarditest ei ole \u00fckski objekt juhuslike s\u00fcndmuste eest kaitstud. Suur osa neist juhtub elektritoide riketest v\u00f5i personali vigadest. Neile kahele tegurile tuleks andmekeskuste ja serveritubade omanikud esmajoones t\u00e4helepanu p\u00f6\u00f6rata, samas kui kliendid peavad m\u00f5istma, et isegi turuliidrid ei saa garanteerida absoluutset usaldusv\u00e4\u00e4rsust. Kui seadmed v\u00f5i pilveteenus teenindavad \u00e4ri jaoks kriitilisi protsesse, tuleks m\u00f5elda varukoha peale.<\/p>\n
