Heroku experienced a major outage on June 10, 2025, lasting over six hours and affecting web platforms worldwide. The incident prevented developers from accessing the platform and disrupted website functionality across multiple regions. This marks the latest in a series of reliability issues for the Salesforce-owned platform, following similar incidents earlier in 20251.
Technical Impact of the Outage
The outage rendered Heroku’s dashboard inaccessible and disrupted application deployments. According to reports on Hacker News, Heroku’s status page initially showed “no issues” despite widespread service interruptions2. The incident appears linked to Salesforce’s underlying infrastructure, mirroring previous AWS-related outages that affected Heroku’s dyno system3. Developers reported mixed application availability, with some services remaining online while others became completely unreachable.
Support channels were overwhelmed during the incident, with many users reporting unresponsive assistance. The lack of transparent communication during the outage has raised concerns about Heroku’s incident management protocols. This follows a pattern of declining reliability noted by users migrating to alternative platforms4.
Platform Limitations and Migration Trends
Heroku’s technical limitations have become increasingly apparent in 2025. The platform lacks WebSocket support and custom VPC capabilities, while its regional hosting options remain limited to North America and Europe4. Cost has emerged as a primary migration driver, with Heroku’s dynos priced significantly higher than comparable offerings from competitors like DigitalOcean and AWS.
| Platform | Key Strengths | Weaknesses | SLA |
|---|---|---|---|
| Heroku | Easy deployment, Salesforce integration | High cost, limited scaling | 99.5% |
| AWS Elastic Beanstalk | Deep AWS integration, auto-scaling | Complex pricing | 99.99% |
| mogenius | Kubernetes-native, multi-region | Steeper learning curve | 99.95% |
| DigitalOcean | Transparent pricing ($5–$100/month) | Fewer managed services | 99.99% |
Migration Considerations and Technical Steps
For teams considering migration, the process involves several technical steps. First, audit all Heroku dependencies using the Heroku CLI. Containerization is recommended for portability across platforms. The choice of destination platform should align with specific requirements:
- Budget-conscious projects: DigitalOcean offers comparable functionality at lower cost points
- Enterprise deployments: AWS or Google Cloud provide better scaling options
- Kubernetes-based workloads: mogenius or OpenShift may be preferable
Data migration from Heroku Postgres can be accomplished using the following commands:
# Export Heroku Postgres data
heroku pg:backups:capture -a myapp
heroku pg:backups:download -a myapp
Security and Reliability Implications
The outage highlights broader concerns about single-provider dependencies in cloud architectures. Multi-cloud strategies have gained traction in 2025, with 60% of enterprises now using multiple cloud providers compared to 35% in 20235. This approach mitigates risk by distributing workloads across different infrastructure providers.
Security requirements have also evolved, with particular attention to data encryption in transit and at rest. Platforms offering confidential computing capabilities, such as IBM Cloud, have seen increased adoption in regulated industries. These technical considerations should factor into any platform evaluation or migration strategy.
Conclusion
The June 2025 Heroku outage underscores the importance of platform reliability and transparent incident communication. While Heroku remains popular for its developer experience, recurring outages and technical limitations have prompted many teams to evaluate alternatives. The migration process requires careful planning but can yield significant improvements in cost, performance, and availability. As cloud platforms continue to evolve, organizations should regularly reassess their infrastructure choices against current requirements and emerging alternatives.
