Even though IT outages have become a common evil, just thinking about a major one makes IT professionals break out in a cold sweat. These can cause serious damage on many levels, from operational to promotional ones. To make matters worse, even the largest organizations in the world can be subject to major outages, even after having dedicated large budgets to prevent them.

Even a few minutes of downtime can lead to a severe crisis affecting an organization’s operations, bottom line, business reputation, and level of customer trust.

To raise industry awareness of the risks associated with outages, we’ve decided to publish a periodical roundup of major IT outages that have taken place during the past few months and gained the worst type of PR imaginable.

We believe that knowing your enemy is the first step towards winning the battle….

Let’s get started - shall we?


April 2019 - Major outage hits five airlines!


Hundreds of flights across the US are delayed after a major IT outage hits at least 5 airline


What happened? An issue with a non-federal program called AeroData, which is responsible for aircraft weight and balance planning, affected several companies’ mainline and regional operations.

The road to recovery: Around 5 hours.

Count the losses: While the total amount was not disclosed, United Airlines alone stated that around 150 of its flights were affected.

Based on our analysis of multiple industry benchmarks, we estimate that this outage caused the loss of tens of millions of dollars.


April 19 - Jetstar flights in Australia experienced significant delays.


Jetstar IT outage took out check-in systems


What happened? An IT outage took down Jetstar’s passenger check-in systems.

The road to recovery: About an hour.

Count the losses: Multiple flights experienced delays, massive queues formed at check-in, and no check-ins could occur throughout the duration of the outage.


April 2019 - Facebook outage is linked to ad buyers


Post-Facebook outage, ad buyers are grappling with out-of-control costs


What happened? This outage was well covered in the press, and we dedicated an article to it: A server configuration issue shut down Facebook, Messenger, WhatsApp, Instagram, and Oculus.

The road to recovery: About 5 hours.

Count the losses: The implications associated with this outage were many. Facebook reportedly earns over $90 million a day in ad revenue, and so the cost of Facebook’s Ad Manager being down for 5 hours was massive. Moreover, ad-buyers continued to report long-term impacts of the outage 2 weeks after it was resolved.


May 2019 - Optus outage affected Netflix, Xbox online, & more


Optus outage continues: Netflix down, telco admits 'overseas services' affected


What happened? The outage denied customers access to many websites, including Netflix.

The road to recovery: At least 4 hours.

Count the losses: The damage to the company’s reputation was massive, as many frustrated customers expressed their anger on social media, demanding a refund.


May19 - Azure outage in Australia

Azure outage turned off Australia for breakfast


What happened? A name server delegation issue with DNS resolution damaged the network’s connectivity.

The road to recovery: A couple of hours.

Count the losses: Even though Azure services couldn’t be reached, it was still running, and this helped minimize the damage. Still, the global incident impacted a whole range of Microsoft cloud services, causing connection problems for core services like Azure, multiple services under the Microsoft 365 umbrella, Dynamics, and DevOps.


May 19 - Salesforce down for 15 hours!

Salesforce’s Pardot went down for 15 hours, exposing data in the cloud


What happened? A faulty Pardot database script interfered with permissions, resulting in Salesforce cutting off all Pardot users until the outage was resolved. The long story short was no access for 15 long hours, during which sales teams were unable to work.

The road to recovery: Around 15 hours!

Count the losses: Critical business and PR damage due to countless Marketing and Sales teams being unable to function across Europe and the US.

As with Salesforce, outages involving any other company that offers its customers online services can have significant financial consequences, like having to provide credits to customers or the payout of penalties. Note that Salesforce shares were down by as much as 3% on Friday, and so loss of value is still another type of financial consequence of an outage to a company like Salesforce.

June 2019 - eBay stopped working


eBay not working: What caused eBay outage?


What happened? The entire eBay website and search function crashed.

The road to recovery: About an hour

Count the losses: The incident heavily affected both eBay itself and its sellers’ businesses. Through the entire outage time bidding on products was disabled.


June 19 - The Cloud brings no guarantee for zero issues


Google’s Cloud outage is resolved, but it reveals the holes in cloud computing’s atmosphere


What happened? A network congestion issue affected several services, including Google Cloud, G Suite, and YouTube.

The road to recovery: About 4 hours.

Count the losses: The outage affected companies that rely on Google’s services, such as Shopify, Snap, Discord, and many others. YouTube suffered a ~10% view drop (think about the ad impressions lost), and Google Cloud Storage suffered a 30% decrease in traffic.

According to TC: “The outage hit everything from the ability to control the temperature in people’s homes and apartments through Google’s Nest to shopping on any service powered by Shopify, Snapchat and Discord’s social networks.”

Mashable provided a quote by one of the many e-shops that were affected: "We probably lost out several thousands of dollars in sales the five or so hours it was down," Stith told Mashable via email. "Not only that, we are having a summer sale right now so we have more orders than we have ever had in the history of the business at once that are not yet fulfilled. Around 500 orders currently not filled."

To summarize, such an outage will likely have long-term implications that are hard to evaluate in the current time. If the largest tech giant in the world, i.e., Google, can suffer a cloud outage, than every other enterprise has the potential to be just as vulnerable.


June 19 - The secondary waves following Google outage


Shopify suffers an outage


What happened? Google’s cloud infrastructure, on which the company depends, went down.

What happened? Issues related to the calendar’s desktop web application. Although this happened in the same month as the major Google outage reported above, it’s a completely different incident. ironically, the issue started immediately after the following tweet was posted:

The road to recovery: Around 3 hours.

Count the losses: It’s hard to put a price tag on canceled meetings across the US, Europe, and parts of South America, but we imagine the damage to be extremely severe.


June 19 - Nationwide outage in Target registries

The road to recovery: Over an hour.

Count the losses: Popular services dealt with the resulting PR damage almost immediately. During the outage, the hashtag #instagramdown was trending on Twitter.

June19 - Netflix experienced issues


Is Netflix down? Streaming service's website experienced 'technical issues' Thursday


What happened? More than half of the complaints reported an issue with the Netflix Website, while around 30% reported connectivity problems.

The road to recovery: A few hours.

This list covered some of the outages that reached the press in April, May, and June 2019. Even the most comprehensive list cannot cover every recent major outage, due to the simple fact that such incidents continue to occur.
