A massive cloud outage stemming from Amazon Web Services’s<\/a> key US-EAST-1 region, its hub near the United States capitol in northern Virginia, caused widespread disruptions of websites and platforms around the world on Monday morning. Amazon’s main e-commerce platform and other properties including Ring doorbells<\/a> and the Alexa smart assistant<\/a> suffered interruptions and outages throughout the morning, as did Meta’s communication platform WhatsApp<\/a>, OpenAI’s ChatGPT<\/a>, PayPal’s Venmo<\/a> payment platform, multiple web services from Epic Games, multiple British government sites, and many others.<\/p>\n

The outages stemmed from Amazon’s \u201cDynamoDB\u201d database application programming interfaces in US-EAST-1, and AWS said in status updates<\/a> that the problem was specifically related to DNS resolution issues. The \u201cDomain Name System\u201d is a foundational internet service that essentially acts as an automatic phonebook lookup to translate web URLs like \u201cwww.wired.com\u201d into numeric server IP addresses so web browsers show users the right content. DNS \u201cresolution\u201d issues occur when DNS servers aren’t accurately connecting these dots and, to keep with the phonebook analogy, are providing the wrong numbers for a given name, or vice versa.<\/p>\n

\u201cBased on our investigation, the issue appears to be related to DNS resolution of the DynamoDB API endpoint in US-EAST-1,\u201d AWS wrote in status updates on Monday. Shortly after the company added: \u201cIf you are still experiencing an issue resolving the DynamoDB service endpoints in US-EAST-1, we recommend flushing your DNS caches.\u201d<\/p>\n

An AWS spokesperson did not immediately respond when asked for details about the nature of the failure. DNS resolution issues can be<\/a> malicious<\/a>\u2014known as DNS hijacking<\/a>\u2014but there is no indication that Monday’s AWS outages were nefarious.<\/p>\n

\u201cWhen the system couldn’t correctly resolve which server to connect to, cascading failures took down services across the internet,\u201d says Davi Ottenheimer, a longtime security operations and compliance manager and a vice president at the data infrastructure company Inrupt. \u201cToday’s AWS outage is a classic availability problem, and we need to start seeing it more as data integrity failure.\u201d<\/p>\n

Problems began around 3 am ET. By 5:22 am ET AWS had applied \u201cinitial mitigations\u201d that were starting to take effect. At 6:35 am ET, Amazon said that it had fully addressed the underlying technical issues but that \u201csome services will have a backlog of work to work through, which may take additional time to fully process.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"A massive cloud outage stemming from Amazon Web Services’s key US-EAST-1 region, its hub near the United States…\n","protected":false},"author":3,"featured_media":318750,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[19],"tags":[2431,5170,2429,160028,712,4995,158,67,132,68],"class_list":{"0":"post-318749","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-internet","8":"tag-amazon","9":"tag-aws","10":"tag-cloud-computing","11":"tag-dns","12":"tag-internet","13":"tag-security","14":"tag-technology","15":"tag-united-states","16":"tag-unitedstates","17":"tag-us"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@us\/115406966253035655","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/318749","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/comments?post=318749"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/318749\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media\/318750"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media?parent=318749"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/categories?post=318749"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/tags?post=318749"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
