Parametrix, a provider of digital business outage solutions, disclosed in a new white paper that although outages of critical cloud services will decline in 2025 after several years of continuous growth, the risk remains significant.
According to the company’s 2025 Cloud Outage Risk Report, after peaking at 244.8 hours in 2024, the total duration of “critical” outage events that result in a complete or major service disruption fell approximately 28% to 175.3 hours in 2025.
The report highlights that despite an overall decrease in downtime, high-impact events persist, affecting some of the most critical cloud regions and major outages to services, including a GCP outage in the us-central1 region in June and an AWS us-east-1 outage in October.
2025 is a notable year as each major cloud provider has experienced at least one impactful event and significant disruption to critical digital supply chain services, namely the global GCP outage on June 12, Cloudflare on August 21, November 18, and December 5, the AWS outage on October 20, and the Azure outage on October 29.
Among AWS outages, the most significant spike and largest event recorded by Parametrix to date was the AWS us-east-1 outage, which was caused by a DynamoDBs DNS automation failure that disrupted connectivity to multiple related services. Shortly after the AWS incident, Azure experienced a global outage of Azure Front Door due to configuration changes.
“This series of events demonstrates that total duration is not the only important factor when measuring the severity of cloud outage events,” the report states. “While total downtime is lower in 2025, the impact of specific events remains high. Every major cloud provider has experienced at least one high-impact event.”
Jonatan Hatzor, co-founder and CEO of Parametrix, commented: “As businesses and the world increasingly rely on cloud-based services, cloud providers’ ability to keep services running will improve in 2025.
He continued: “However, after a relatively eventful first half, outages resumed and reached higher levels in the second half. We experienced significant outage events across data centers operated by all three major cloud providers.
“If average monthly downtime remains unchanged in the first half of 2026, we expect the 12 months from July to June to be record-breaking. As dependencies, and thus the value at risk, continue to escalate, ensuring financial protection against digital supply chain disruptions is more important than ever.”
