SAN MATEO, Calif., Sept. 02, 2026 (GLOBE NEWSWIRE) — SIOS Technology Corp., an industry leader in application high availability (HA) and disaster recovery (DR), today announced the results of its 2026 State of Application Resilience Survey, revealing that despite widespread adoption of HA/DR technologies, most enterprises continue to experience downtime, struggle with increasingly complex hybrid infrastructures, and lack confidence in their existing resilience strategies.
The survey gathered responses from more than 250 IT leaders across North America and the United Kingdom, representing predominantly large enterprises across industries including healthcare, financial services, manufacturing, retail, government and technology. The research examined how organizations protect mission-critical applications from downtime and disasters while identifying emerging priorities for HA/DR investments.
Key findings include:
- Downtime remains a persistent problem. Seventy-six percent of organizations experienced at least one outage lasting more than 10 minutes over the past year despite having HA/DR protection in place, highlighting the limitations of many existing failover strategies.
- Hybrid and multicloud environments have become the norm. Nearly seven in ten organizations now run critical applications across hybrid infrastructures, while only 2% operate exclusively on-premises, increasing the complexity of maintaining application availability across diverse environments.
- Organizations lack confidence in their resilience strategies. Only about half of respondents said they were satisfied with their current HA/DR solutions, while many remained neutral or dissatisfied, suggesting existing solutions are falling short of enterprise expectations.
- Disaster recovery testing remains inconsistent. Only 7% of organizations perform monthly DR testing, while one-third test just annually and 22% don’t know how frequently testing occurs, creating significant recovery risk.
- Cybersecurity is reshaping HA priorities. Seventy-two percent of respondents either already use or would consider using HA clustering to streamline patch management, reflecting growing recognition that application availability and cyber resilience are increasingly interconnected.
- Complexity has overtaken cost as the biggest challenge. Configuration and management complexity ranked as organizations’ top HA/DR challenge, followed closely by integration across increasingly heterogeneous IT environments.
- Investment priorities continue to rise. Improving disaster recovery protection ranked second only to cybersecurity among planned IT investments over the next 18 months, demonstrating that organizations are actively budgeting to strengthen resilience.
“The survey makes it clear that organizations have invested heavily in protecting mission-critical applications, but many are still experiencing downtime and operational complexity that traditional HA/DR approaches weren’t designed to address,” said Masahiro Arai, COO of SIOS Technology Corp. “As enterprises adopt hybrid and multicloud architectures while facing increasing cybersecurity threats, application resilience has become far more than failover. Organizations need intelligent, application-aware clustering solutions that simplify operations, accelerate patching, improve cyber resilience and ensure continuous availability across increasingly complex environments.”
The survey also found that Windows remains the dominant operating system for mission-critical applications, but organizations increasingly manage mixed Windows and Linux environments, reinforcing the need for cross-platform HA solutions. Respondents also indicated growing interest in application-aware clustering technologies that can simplify operations while improving resilience across heterogeneous infrastructures.
