In a significant disruption to global development operations, Atlassian’s Bitbucket Cloud experienced a severe outage on January 21, 2025, affecting millions of developers worldwide. The incident, which Atlassian described as a “hard down,” began at 15:30 UTC and impacted core services, including Git operations, website accessibility and CI/CD pipelines.

The root cause was identified as a saturated database issue, demonstrating how performance remains critical even in modern cloud architectures. While Atlassian’s engineering teams successfully mitigated the primary problem by 18:02 UTC, residual effects continued to ripple through dependent services, particularly affecting Bitbucket Pipelines.

For DevOps teams, the outage served as a stark reminder of the cascading effects that version control system disruptions can have on development workflows. Microsoft reported that its Visual Studio App Center experienced service interruptions due to the Bitbucket outage, highlighting the interconnected nature of modern development toolchains.

“On January 21, 2025, Bitbucket experienced a temporary outage that impacted some Cloud customers,” an Atlassian spokesperson confirmed. The company’s response highlighted their focus on rapid resolution, with services returning to regular operation by 20:08 UTC. However, the incident affected Bitbucket’s extensive user base of approximately 10 million developers, who collectively manage tens of millions of repositories.

The outage’s impact extended beyond just code access. Teams lost access to:

• Website and API functionality
• Git operations via both HTTPS and SSH
• Authentication and user management systems
• Webhook deliveries and automated integrations
• CI/CD pipeline operations
• Source code downloads and Git LFS operations

This comprehensive service disruption emphasizes the importance of having contingency plans for source control outages. While distributed version control systems like Git provide local copies of repositories, the inability to push, pull, or collaborate through the central platform can effectively halt development operations for teams relying heavily on cloud-based workflows.

For organizations leveraging DevOps practices, the incident underscores several key considerations:

• First, while cloud services offer tremendous advantages in terms of scalability and maintenance, they introduce dependencies that require careful risk management. Teams should consider implementing backup procedures for critical operations that rely on cloud-based services.
• Second, the outage demonstrates how database performance remains critical to cloud service reliability. Even with modern cloud architectures, database saturation can still lead to system-wide failures, suggesting the need for robust monitoring and early warning systems.
• Finally, the incident highlights the importance of transparent communication during outages. Atlassian’s clear status updates and acknowledgment of the “hard down” situation helped teams understand the scope of the problem and plan accordingly.

As development teams increasingly rely on cloud-based services for daily operations, understanding and preparing for potential disruptions becomes crucial. While Atlassian’s quick response and resolution minimized the long-term impact, the incident serves as a valuable reminder for DevOps teams to regularly review their dependency chains and maintain contingency plans for critical services.

This outage may prompt more organizations to evaluate their disaster recovery procedures and consider implementing additional redundancies for critical development operations. As we build more interconnected development ecosystems, resilience planning becomes not just a best practice, but a necessity for maintaining consistent development workflows.
