<li>Amazon Web Services experienced an outage on Tuesday that caused other apps, like Netflix, Coinbase, and Tinder to see slower services.</li>
<li>An internal AWS analysis pointed to traffic congestion across multiple network devices in the Northern Virginia region.</li>
<li>But employees are still trying to figure out the root cause of the problem and seem confused by the depth of the outage, which has affected all parts of AWS&#8217; global operations in some capacity.</li>
</ul>
<p>As Amazon Web Services experienced one of the largest <a href="https://www.businessinsider.com/amazon-servers-are-down-and-its-affecting-dozens-of-services-2021-12" data-analytics-module="body_link">outages</a> in company history on Tuesday, more than 600 employees joined an emergency conference call to assess the root cause of the service disruption.</p>
<p>The main culprit: a sudden increase in traffic that caused congestion across multiple network devices in Northern Virginia, the biggest region for AWS data centers.</p>
<p>The company had initially pegged the &#8220;root cause&#8221; of the outage on &#8220;a problem with several network devices within the internal AWS network,&#8221; according to a screenshot of an internal AWS communique from Tuesday morning obtained by Insider. &#8220;Specifically, these devices are receiving more traffic than they are able to process, which is leading to elevated latency and packet loss for the traffic traversing them.&#8221;</p>
<p>The problems are ongoing as of Tuesday afternoon, and have resulted in hours of service disruptions across the web, causing some of the world&#8217;s biggest online services, including Disney Plus, Netflix, and even Amazon&#8217;s own e commerce store to experience widespread glitches and slowdowns. The list of companies that saw outages on Tuesday include Spotify, Zoom and Airbnb, to name a few.</p>
<section class="content-recommendations-in-post-module-1"></section>
<p>While the outage was linked to a disruption in Northern Virginia, it has disrupted all parts of AWS&#8217; global operations in some capacity. Moreover, Amazon&#8217;s retail and delivery networks, which rely on AWS&#8217; tools, were in some cases thrown into a screeching halt.</p>
<p>The outage snarled Amazon&#8217;s internal warehousing and logistics operations in the midst of the holiday shopping season. Some warehouse workers and drivers were sent home as the company&#8217;s internal communications, delivery routing and monitoring systems stalled.</p>
<p>The network issue &#8220;specifically impacted&#8221; Amazon&#8217;s internal DNS servers. As of 2:04 p.m. Seattle time, the company did not have an estimate on when the system would be fully operational, according to a message on <a href="https://status.aws.amazon.com/" target="_blank" rel="nofollow noopener" data-analytics-module="body_link">the public AWS status console</a>.</p>
<p>A separate internal note said &#8220;firewalls are being overwhelmed by an as of yet unknown source,&#8221; adding that the AWS networking teams are working on &#8220;blocking the traffic from the top talkers/offending hosts at the firewall.&#8221;</p>
<p>Activity from Amazon&#8217;s real-time digital advertising auction may be responsible for much of the traffic overwhelming the firewall, according to internal Slack messages seen by Insider.</p>
<p>In an email to Insider, Amazon&#8217;s spokesperson said, &#8220;There is an AWS service event in the US-East Region (Virginia) affecting Amazon Operations and other customers with resources running from this region. The AWS team is working to resolve the issue as quickly as possible.&#8221;</p>
<p>Even inside AWS, however, information on the outage remains sketchy. As engineers and executives worked decode the issue on a 600-person conference call, led by AWS&#8217;s VP of infrastructure Peter Desantis, rumors spread among staff. One AWS employee speculated that the outage was caused by an &#8220;orchestrated DNS attack,&#8221; while another employee downplayed those concerns, saying it was more of an &#8220;internal thing&#8221; related to networking and firewall saturation.</p>
<p>&#8220;It&#8217;s the fog of war,&#8221; said an AWS manager.</p>
<p>In a message sent just before 2:00 p.m. Pacific Time, the company&#8217;s internal communications team told employees it was &#8220;beginning to see significant recovery for AWS service availability in the US-EAST-1 Region.&#8221; The division&#8217;s &#8220;most senior engineers&#8221; are continuing to monitor the issue, including &#8220;identifying the specific traffic flows that were leading to congestion within these devices,&#8221; the note said.</p>
