Over the weekend, we responded to the critical "DirtyFrag" Linux vulnerability (CVE-2026-43284 and CVE-2026-43500) by deploying an emergency kernel patch across all regions.
While our systems are not affected by the RxRPC vulnerability (CVE-2026-43500) as we don't compile that kernel module, we were affected by the IPsec ESP vulnerability (CVE-2026-43284) and needed to apply patches immediately.
To protect your data and minimize exploitation risk during the rollout, we temporarily restricted SSH and deployment access and performed brief service restarts.
While this vulnerability "only" provided root access within affected systems, we recognize that such exploits are typically used as the first step in a chain of attacks, potentially leading to container escapes and broader infrastructure compromise. Given this risk, we chose to err on the side of caution by implementing temporary access restrictions during our update window.
We understand this disruption was inconvenient, and the decision to disable SSH access was not made lightly. However, we believe these swift and decisive actions were essential to safeguarding your systems and data. Our priority is always to maintain the security and integrity of your infrastructure.
All services have now been fully restored, and you can access your projects and deployments as normal. If you're still experiencing any issues, please don't hesitate to contact our support team. We appreciate your patience and understanding as we work to keep your hosting environment secure.

We are aware of the recently disclosed https://t.co/DGtKxwwvN7 vulnerability (CVE-2026-31431) and want to assure our customers that Upsun systems are not affected.
The module targeted by this vulnerability is disabled in our platform. We run hardened Linux kernels in which we only enable the components required for our services, minimizing the attack surface. As such, there is no risk of exploitation, and no action is required on your part.
We remain committed to the security of our products and will continue to monitor for any developments. If you have any questions or concerns, please do not hesitate to contact our support team. ✨
Today, India takes a defining step in its civil nuclear journey, advancing the second stage of its nuclear programme.
The indigenously designed and built Prototype Fast Breeder Reactor at Kalpakkam has attained criticality.
This advanced reactor, capable of producing more fuel than it consumes, reflects the depth of our scientific capability and the strength of our engineering enterprise. It is a decisive step towards harnessing our vast thorium reserves in the third stage of the programme.
A proud moment for India. Congratulations to our scientists and engineers.
It's open source now. Run it locally on your Mac and Apple Watch and get haptics once Claude Code completed the task. Thanks everyone for the amazing support on the app, that was honestly unexpected.
