GitHub, the platform where the vast majority of open-source crypto projects live, is having a very bad year. The Microsoft-owned code hosting service has been battered by a surge of outages, security vulnerabilities, and what current and former employees describe as deepening internal dysfunction.
The numbers paint an ugly picture
GitHub recorded 109 incidents in the first half of 2025. That’s a 58% increase compared to the same period a year earlier, totaling more than 330 hours of downtime.
In April 2026 alone, the platform reported 10 separate incidents causing performance degradation across its services. One of those, on April 1, took down code search entirely.
A major outage on February 9-10, 2026, knocked out GitHub Actions, pull requests, notifications, and Copilot features all at once. Actions is the CI/CD pipeline that many teams rely on to automatically test and deploy code.
HashiCorp co-founder Mitchell Hashimoto said GitHub has become “no longer a place for serious work.”
A recent security incident revealed that GitHub’s own internal code repositories were compromised after an employee installed a “poisoned” VS Code extension on their device. A separate remote code execution vulnerability disclosure added to the pile.
Why crypto should care, a lot
Major projects like Uniswap and Compound host their code repositories primarily on GitHub. So do thousands of other protocols across Ethereum, Solana, and virtually every other chain worth mentioning.
A 2023 academic study found a measurable connection between robust GitHub activity, things like forks, watches, and issue tracking, and positive price movements in related cryptocurrencies.
Protocol upgrades get delayed. Critical security patches sit in limbo. New features miss their launch windows. For DeFi protocols managing billions in total value locked, a delayed security patch isn’t an inconvenience. It’s an attack surface.
Leadership questions and the Microsoft factor
Microsoft acquired GitHub for $7.5 billion in October 2018. CEO Thomas Dohmke has led the company since 2021, and the sustained decline in reliability has happened squarely on his watch. Current and former employees have described internal challenges that suggest the problems run deeper than infrastructure capacity.
GitLab, GitHub’s closest rival, stands to benefit most from any migration of developer teams. Self-hosted Git solutions are also getting a second look from teams that can’t afford the downtime risk.
What this means for investors
Token valuations for projects like Uniswap, Compound, and other DeFi protocols are partially driven by development velocity. When that velocity gets disrupted by platform failures, the downstream effects can show up in delayed roadmap milestones and weakened community sentiment.
The 58% year-over-year increase in incidents isn’t a blip. It’s a trend. Watch for whether major crypto projects begin publicly announcing moves to GitLab or self-hosted infrastructure, and whether GitHub’s incident rate stabilizes or continues climbing.
