For today’s enterprises, system downtime can significantly harm revenue, reputation, and overall resilience. Even a brief disruption can translate into financial losses ranging from thousands to millions of dollars. When critical systems, such as databases, customer portals, or platforms handling internal operations and online transactions fail, the impact is felt across both internal teams and external stakeholders, who demand always-on apps and no disruptions.
This article will examine the rising costs associated with downtime and explore strategies organizations can employ for protection. We’ll highlight the role of data infrastructure as a critical role in mitigating downtime. Additionally, we’ll explore how EDB Postgres® AI (EDB PG AI) support for high availability and distributed architectures helps organizations design systems that stay online, even during unexpected disruptions.
What is the cost of downtime?
When people hear downtime, they usually think about a website crashing or a web page taking a few minutes to load. However, downtime is a broader term referring to any interruption in the availability or performance of the systems your business depends on.
For businesses, downtime can mean the following:
- Application outages prevent customers from logging in, completing transactions, or accessing critical services.
- Database downtime halts your daily operations, preventing teams from processing orders, generating reports, and meeting compliance requirements.
- System failures disrupt internal workflows, employee productivity, and customer engagement.
More than revenue loss
The full cost of downtime includes productivity losses caused by employees waiting idly or customer service teams unable to do their jobs. It also includes service-level agreement (SLA) violations and contractual penalties when your services fail to meet promised uptime.
Downtime can also result in customer dissatisfaction, leading to long-term damage to your brand’s reputation and customer trust. If you don’t meet compliance or regulatory standards, you may also face hefty fines, especially if your business is in the financial, healthcare, or government sectors.
Calculating downtime
There is a simple formula to calculate the total cost of downtime. This equation is:
Downtime cost = Minutes of outage x cost per minute
That cost per minute depends on your business model and operational setup. To estimate your number, consider the following:
- Average transaction value and volume, such as missed sales per minute or hour
- Employee wages and benefits during downtime
- Lost advertising spend, such as paid campaigns driving traffic to nonfunctioning systems
- SLA penalties or credits owed to customers
- Customer churn risk or lost revenue
Using this formula, it is easy to see how 15 minutes of downtime can quickly cost hundreds of thousands of dollars in lost revenue. Mission-critical databases are at the heart of this calculation. If your database goes down, every system that relies on it is affected, from payment systems to customer support portals.
That’s why enterprises are investing in high availability (HA) and real-time replication at the database layer. EnterpriseDB (EDB) offers capabilities, such as multi-region replication, proactive monitoring and recommendations, and active-active architectures with distributed HA clusters, that are designed to support always-on apps and keep recovery times as close to zero as possible.
Planned downtime vs. unplanned downtime
Not all downtime is the same. To reduce costs, enterprises need to understand the difference between planned downtime and unplanned downtime.
Planned downtime
Planned downtime happens when IT teams schedule systems to go offline for maintenance, upgrades, or migrations. Examples include applying critical security patches, performing hardware upgrades, migrating workloads to new environments, and rolling out new features.
These windows are scheduled in advance, which means they’re often done during off hours and communicated to customers ahead of time. While still disruptive, planned downtime can be managed to minimize impact, and it often helps to prevent unexpected failovers down the line.
Unplanned downtime
Conversely, unplanned downtime occurs when systems fail unexpectedly. Common causes include:
- Hardware failures
- Misconfigurations or software bugs
- Network outages
- Cyberattacks or security breaches
- Database crashes or replication lag
Unplanned downtime is more expensive than planned downtime because organizations have little to no warning, customers lose access without notice, and internal teams cannot do their jobs.
Both matter
While planned downtime is easier to manage, it can still be costly if it occurs too frequently or lasts too long, especially for enterprises with global customers operating in multiple time zones. For industries such as e-commerce, finance, or SaaS, even a maintenance window at 2 a.m. local time may overlap with peak hours elsewhere in the world.
Unplanned downtime holds the biggest risks. These incidents are difficult to predict, harder to communicate, and more damaging to brand trust and customer experience.
Measuring and reducing downtime
To measure and reduce the risk of both types of downtime, your enterprise should:
- Track both planned and unplanned downtime to reduce your true exposure.
- Measure frequency and duration to identify systematic risks.
- Invest in high availability and fault tolerance to reduce both types of downtime.
How much does downtime cost?
Downtime costs are high, and they are continuing to rise. While every business will have a unique cost per minute, industry benchmarks paint a sobering picture:
- Information Technology Intelligence Consulting (ITIC) conducted a 2024 survey that found that, for 90% of midsize and large companies, just one hour of downtime exceeds $300,000, with 41% reporting losses between $1 million and $5 million per hour.
- Uptime Institute’s global Annual Outage Analysis 2024 reported that 54% of major outages cost more than $100,000, and nearly one in five cost more than $1 million.
- For Fortune 1000 companies, multiple studies estimate the average hourly cost of downtime at $1–$5 million, depending on industry and system.
These benchmarks are averages. A smaller company may not lose $1 million per hour, but downtime can still hit harder proportionally. For example, if a midsize SaaS provider loses $50,000 in revenue from a two-hour outage, that might represent an entire quarter’s profit margin.
Additionally, costs scale with company size, complexity, and digital maturity. If a large company uses a database for its essential workflows, an outage’s cost can multiply significantly.
Factors that influence downtime costs
While the above benchmarks provide a useful starting point, the actual cost of downtime varies widely depending on a company’s industry, size, and infrastructure. For some organizations, a short outage may be an inconvenience. However, for others, it may be catastrophic. How costly downtime is depends on several factors:
Business size and risk exposure
Large enterprises face the highest dollar costs. High transaction volumes, global customer bases, and contractual obligations make every minute offline expensive. Small and midsize organizations may see lower absolute costs but higher relative impact. A few thousand dollars lost in an outage can erase an entire month’s profit or stall growth initiatives.
System architecture
Your architecture has a direct impact on downtime risk. Monolithic systems may fail in ways that take entire services offline. Conversely, distributed and cloud-native systems add resistance but increase interdependence, which can create more potential points of failure.
Additionally, databases without high availability are especially vulnerable. In these systems, a single-node failure can ripple across the entire application or system, leading to lost transactions, corrupted data, or extended outages.
Other factors
There are other variables that can determine how costly downtime will be for your organization. These include:
- Business model: Cloud-native companies, SaaS platforms, and online retailers are highly sensitive to downtime, while manufacturing may feel more impact from enterprise resource planning (ERP) or supply-chain system outages.
- Industry: For highly regulated industries, such as the government, healthcare, finance, and telecom, downtime can lead to a loss of trust and hefty fines due to a lack of compliance. For other industries, such as e-commerce or sales, even brief outages during peak seasons can cost millions in lost sales.
- Geography: Enterprises with global operations can’t rely on local off hours. Maintenance and upgrades can be done during times when your business is closed—but these might be the peak business hours of your global customers.
- Uptime expectations: Customers now expect 24/7 availability. A few minutes of downtime can feel like an eternity in fiercely competitive sectors.
Downtime cost is about architecture, compliance, and customer experience. This is why many enterprises turn to EDB PG AI.

The impact of downtime costs
The cost of downtime is more than financial. It can have cascading effects across revenue, productivity, compliance, and brand reputation.
Business disruption
When core systems are unavailable, entire business workflows can stop. In industries such as SaaS, finance, and e-commerce, downtime prevents customers from accessing services, completing transactions, or receiving support. Even short disruptions can cause customer frustration and open the door for competitors.
Revenue loss
Every missed transaction represents immediate, measurable loss. For subscription-based services, downtime accelerates churn rates and increases the likelihood of customers cancelling or switching providers. For internal-facing applications such as enterprise resource planning, downtime slows order fulfillment and cash flow.
Internal productivity loss
Outages also impact employees across departments, as they are left waiting or improvising manual work-arounds. Meanwhile, IT and engineering teams shift focus from planned initiatives to problem-solving and recovery.
Regulatory and SLA penalties
In regulated industries, downtime often means noncompliance, as in:
- Finance: Missed transaction deadlines may trigger fines or investigations.
- Healthcare: Outages can cause violations and compromise patient care.
- Public sector: Service interruptions can erode public trust.
On top of that, SLA penalties with customers or partners can add contractual costs, which can compound financial damage.
Brand recognition and trust
One of the hardest costs to quantify is brand impact. A single major outage can make headlines, trigger social media backlash, and create a lasting perception of unreliability. Customers, investors, partners, and other stakeholders may start to question your organization’s stability. In competitive markets, that reputational hit can linger after your systems are back online.
Why these costs keep rising
Every year, enterprises add more applications, services, and extensions. What used to be a handful of mission-critical systems is now a complex, interdependent web. This means that a failure in one system can cascade quickly, dependencies on third-party applications and servers can introduce new risks you can’t control, and 24/7 customer expectations create pressure to keep everything running.
In fully digital industries, an outage cuts off revenue. With fewer physical backups, downtime leaves organizations exposed. Additionally, the combination of more interconnected systems, higher dependency on digital services, and increasing complexity is pushing downtime costs higher each year.
While the stakes of downtime are rising, the right infrastructure can help mitigate your risk. EDB’s enterprise Postgres solutions are a future-proof investment in uptime resilience with a 99.999% uptime guarantee and geo-distributed clustering that reduces regional outage risks.
Strategies to minimize downtime costs
Downtime will always have a cost. However, with the right strategies, enterprises can reduce both the frequency of incidents and their impact. The key is to take a comprehensive approach.
1. Build and test a disaster recovery plan
A well-documented disaster recovery plan (DRP) is the foundation of organizational resilience. Enterprises should ensure their plan has the following:
- Clear and defined recovery time objectives (RTOs) and recovery point objectives (RPOs)
- Regularly running failover drills to ensure readiness
- Extended coverage beyond infrastructure to include databases, applications, and user access
EDB provides robust backup, recovery, and replication tools. Our solutions can help restore databases quickly and reliably as part of a tested DRP.
2. Communicate effectively during incidents
Clear, transparent communication, both internally and externally, helps reduce confusion and protect brand trust. Best practices include:
- Real-time dashboard for internal teams
- Automated alerts via Slack, PagerDuty, or similar tools
- Customer-facing status updates on social media or prerecorded messages
The best way to minimize downtime is to stop incidents before they occur. Continuous monitoring and observability provide early warning signs. You can monitor database performance with tools such as Prometheus or Elastic (ELK) Stack.
Additionally, you can automate failover for faster recovery without human intervention and patch proactively to prevent vulnerabilities from causing outages.
EDB PG AI provides a single pane of glass to observe your databases, and it integrates with your monitoring and alerting systems. This makes it easier for teams to see database health in real time and respond before issues escalate.
3. Remove single points of failure
Single-node databases and monolithic systems are common sources of costly downtime. Enterprises should design infrastructure with redundancy at every layer, using the following best practices:
- Use clustering and replication to eliminate single nodes.
- Deploy across regions to mitigate localized outages.
- Ensure that load balancing is in place to handle traffic spikes.
EDB PG AI delivers active/active fault tolerance across multiple nodes and geographies. This distribution helps keep systems available even if individual servers fail.
4. Conduct postmortems
The most successful enterprises use downtime incidents as learning opportunities. A strong postmortem process ensures that teams understand root causes to help prevent recurrences. This process includes:
- Documenting incidents clearly
- Sharing findings across teams
- Tracking key performance indicators (KPIs), such as mean time to recovery (MTTR)
- Treating outages as opportunities to strengthen processes
With advanced logging, observability, and HA tooling, EDB makes it easier to pinpoint causes of downtime, which you can then use to improve your systems.
