The trust boundary moves inward

The important failures are happening inside the platforms.

Yesterday’s news was not just another security incident, another cloud outage, or another giant IPO filing. It was a reminder that the trusted interior of the stack is becoming the contested surface: employee machines, cloud account status, internal repositories, routing control planes, and compute contracts between nominal competitors.

GitHub’s breach came through a developer workstation. GitHub says it detected and contained a compromised employee device on May 18 involving a poisoned third-party VS Code extension. Its current assessment is that the attacker exfiltrated GitHub-internal repositories only, and that the attacker’s claim of roughly 3,800 repositories is “directionally consistent” with the investigation. GitHub says it has no evidence of impact to customer information stored outside its internal repositories, while noting that some internal repositories can contain customer-related material such as support excerpts.

The lesson is not “GitHub is unsafe.” It is that the developer toolchain is now a supply-chain perimeter. A code editor extension on one employee machine can become a path into internal source. GitHub’s response was the right kind of boring: remove the malicious extension, isolate the endpoint, rotate critical secrets, analyze logs, and keep monitoring. But the incident makes the real boundary visible. For a developer platform, internal repos are not just internal. They are the map of how the platform works.

Railway’s outage was a vendor failure that became an architecture failure. Railway’s postmortem says Google Cloud incorrectly suspended Railway’s production account on May 19. That took down GCP-hosted infrastructure supporting the dashboard, API, control plane, databases, and parts of the network. The deeper problem was that Railway’s edge proxies depended on a GCP-hosted control plane API to populate routing tables. While cached routes held, some workloads on Railway Metal and AWS stayed reachable. When the cache expired, the outage cascaded across regions and clouds.

Railway’s most important sentence is the accountable one: “Your customers don’t care whether the failure was Google or Railway; they see your product.” That is the correct frame. Multi-cloud is not resilience if the control plane still has a hot-path dependency on one provider. Railway says it will remove that dependency, extend high-availability database shards across AWS and Metal, and remove Google Cloud services from the data plane’s hot path.

SpaceX’s IPO filing turns AI compute into the business model. TechCrunch reports that SpaceX’s public S-1 shows a company no longer legible as only rockets and Starlink. SpaceX reportedly generated more than $18 billion in 2025 revenue, lost about $4.9 billion, and saw Starlink produce more than half of revenue. But the filing also makes AI central: TechCrunch says SpaceX directed about 60% of 2025 capital spending, roughly $20 billion, to its AI division after xAI was merged in, and claims a $28.5 trillion total addressable market, with $22.7 trillion attributed to enterprise AI applications.

The compute detail is sharper. TechCrunch separately reports that Anthropic will pay xAI $1.25 billion per month through May 2029 for compute, with either side able to terminate on 90 days’ notice. If accurate, that makes xAI both a frontier-model competitor and a kind of neocloud supplier to a rival. The line between AI lab, infrastructure provider, and customer is blurring.

The pattern: platforms are competing on the visible product, but the risk and leverage sit inside the invisible machinery. Poisoned extensions, account suspensions, routing caches, internal repos, GPU oversupply, compute resale — these are not side details. They are the new operating surface.

The question to ask of every AI platform now is not only “what can the model do?” It is: what machines, permissions, contracts, secrets, and control planes does the model depend on, and what happens when one of them is wrong?
