Unplanned downtime can cost you millions (or even billions), disrupt workflows, and weaken customer trust. No production environment is immune, especially if you are relying on an age-old environment.
What if your production line stops for hours or even days? The consequences multiply across your operation and echo through your revenue.
This article breaks down the risk. First, we explore the root causes and costs. Then, we outline precise steps and proven strategies to reduce the risk of unplanned downtime. The spotlight? Aging legacy hardware – a silent but serious liability.
What is Unplanned Downtime?
Unplanned downtime refers to an unexpected halt to normal business activities. Simply put, it is a period when systems, processes, or machinery stop functioning without prior scheduling.
For example, in manufacturing, unplanned downtime can happen due to legacy hardware failures. This in turn, can impact the entire production and result in delayed shipments – ultimately leading to significant financial losses.
Unlike planned downtime for scheduled maintenance, these sudden disruptions catch operations off guard. Losses grow with every passing minute.
Key drivers of unplanned downtime include:
- Legacy hardware
- Human error
- Cyberattacks
- Software or application failures
Mostly, legacy hardware drives a substantial share of these incidents. With each passing year, the risk amplifies. So, downtime can hinder business operations for any enterprise that still depends on end-of-life hardware.
When unplanned downtime actually hits legacy systems, IT teams find themselves clueless and have no clear path to recovery. In that moment of crisis, they regret not having planned earlier to avoid the downtime.
Real-World Examples of Companies Affected by Unplanned Downtime
How does downtime look in reality? Consider the following incidents that show how even the largest companies face disruption:
Facebook:
In 2021, a routine data center procedure backfired. Engineers accidentally disconnected the platform’s infrastructure, sending Facebook offline for hours. Billions of users lost access. Media coverage intensified, and the company’s overreliance on proprietary infrastructure came under scrutiny.
JPMorgan Chase & IT Enterprises:
Even the financial sector suffers. JPMorgan Chase has suffered repeated service outages and latency. Across IT, unplanned downtime impacts productivity and trust. The global toll? Over $400 billion in annual losses.
Southwest Airlines:
They were hit hard by an IT breakdown in December 2022. Flights were grounded and passengers were stuck. Financial damages led to an estimated $725 million in lost revenue and regulatory fines of $140 million.
Toshiba & Western Digital:
At Japanese plants, only 13 minutes of downtime in July 2019 led to shutting down NAND flash memory production at key facilities and reverberated through the world’s supply chains.
Renesas Electronics:
A fire in one cleaning room shut down a chip factory. The effects spread to automakers worldwide – Toyota, Honda, Nissan, and many more, awaiting delayed components.
Samsung Electronics:
Twice in two years, brief outages led to an outsized impact. In 2018, a 30-minute blackout cost Samsung $43 million. Two years later, a minute-long power loss stopped operations for almost three days.
How Does Outdated Hardware Result in Unplanned Downtime?
Legacy hardware becomes a stumbling block and, eventually, a point of failure. For instance, legacy systems drive nearly 20% of downtime in semiconductor manufacturing. A recent study found that 82% of organizations have experienced downtime in the last three years, costing them up to $260,000 per hour.
Here is how aging servers are causing unplanned downtime:
Cybersecurity Risks and Vulnerabilities
Obsolete hardware lacks the latest security updates, making it extremely prone to cyber threats. The result could be system failures as well as long production downtimes.
Incompatibility Issues
Modern digital initiatives demand compatibility. But legacy hardware is a barrier to that. When your competitors are embracing innovation, legacy servers can stall you because they do not integrate well with AI, IoT, and cloud.
Lack of Support
When the original equipment manufacturer stops supporting, you face a problem. Rare parts are hard to find. The shortage of skilled engineers is even greater. You invite severe failures with every repair. Downtime? As time passes, the probability increases. It is difficult to find a quick fix or a replacement.
Maintenance Challenges
Old systems cost more to maintain. As breakages grow, so does expense. Without vendor support, even minor failures balloon into major crises. Inefficient maintenance tied to legacy infrastructure is expensive.
Regulatory Non-Compliance
Regulatory standards don’t stand still. Older hardware usually can’t keep up, exposing businesses to fines or security breaches. Compliance lapses don’t just cost money, they damage trust. Picture this: a single breach resulting in penalties and lost customers. Can you afford that?
How to Calculate the Cost of Unplanned Downtime
Understanding true impact means calculating more than the surface costs. Downtime drains revenue, productivity, and even future potential. Here’s the standard formula:
Now, let’s break down these factors:
Lost Revenue: (Hourly Revenue) x (Hours of Downtime)
Example: For some, that means $2.3 million per hour, as in the automotive sector. The cost for a duration of two hours would be approximately $4.6 million.
Lost Productivity: (Number of Affected Employees) x (Average Hourly Cost) x (Downtime Hours)
The productivity lost by employees is significant if they are unable to work. Each idle resource adds one to the total. Due to this, real costs are often underestimated.
Tangible Expenses:
- Replacement parts and repairs
- Overtime for technical staff
- Loss of goods due to halts
- Emergency shipping costs
Intangible Expenses:
- Brand and reputation damage
- Lower employee morale
- Missed contracts or deals
- Supply chain disturbance
6 Steps to Fix Unplanned Downtime
Now that you understand the risks, how can you mitigate them? Shift from a reactive to a proactive strategy. Follow these six actionable steps to enhance resilience and reliability.
1. Audit All Legacy Systems
Start where you stand. Evaluate your entire legacy environment. Inspect the dependencies, record the vulnerabilities and analyze for performance considerations. This is your level of risk, and it shows you right where you are and where you need to be.
2. Leverage virtualization and hardware emulation
Emulation solutions, like Stromasys Charon, move legacy workloads to modern x86 platforms. You retain your legacy software without rewriting or recertifying it. The best part? You no longer have to deal with the legacy hardware risk. But at the same time, you keep your business-critical legacy applications serving your business for decades.
3. Right-Size and Configure Modern Systems
You need to fit the resources for your new virtual system. So, get it right when you build a new virtual system – allocate the CPU, memory and storage according to your application’s requirements. This allows you to do things better and more efficiently rather than just copy a standard setup.
4. Plan Data Migration Carefully
For large data sets, it is non-negotiable to plan carefully when moving a legacy data set to a new platform. Sending terabytes of data over a network can be time-consuming. Therefore, it is necessary to evaluate your options carefully, from physical data transfer medium to dedicated network lines. Choose an approach that works for the timeline and goals of your project.
5. Ensure User Connectivity and Security
Post-migration, there must be an uninterrupted and secure connection between your users and the application. Meet the security requirements of your organization on the new platform. Take into account the number of users and the bandwidth available to ensure satisfactory performance.
6. Test Every Single Thing Extensively
Ideally, before going live, you must verify that the new system works as intended. Prepare a comprehensive test plan that covers common and critical user functions. Run these tests on the original system to create a baseline. Run them again on the new emulated system. Check the results to make sure everything works as expected.
