Business Insider reported Tuesday, citing two people familiar with the plans, that Microsoft has provisioned extra cloud computing capacity from Amazon Web Services (AWS) to support GitHub after AI-driven activity triggered repeated service incidents. GitHub COO Kyle Daigle disclosed in April 2026 that the platform was processing 275 million commits per week — on pace for 14 billion in 2026, compared with 1 billion for all of 2025 — while GitHub Actions weekly compute minutes reached 2.1 billion in a single week in early 2026, up from 500 million in 2023. The Register counted nine GitHub service incidents in May alone. GitHub separately paused new individual sign-ups for Copilot Pro, Pro+, and Student tiers, with VP of Product Joe Binder citing agentic workflows that had “fundamentally changed Copilot’s compute demands.” A Microsoft spokesperson confirmed a multi-cloud approach without naming AWS by name, attributing the strain to “the incredible spike in agentic development” since late 2025.
GitHub has operated on mixed infrastructure since Microsoft acquired it for $7.5 billion in 2018, with a standing plan to complete a full Azure migration by 2027. Microsoft said it is both accelerating that Azure transition and exploring multi-cloud options to secure the capacity and elasticity GitHub now needs, framing the AWS arrangement as an operational response rather than a strategic retreat. The move echoes a constraint Microsoft CFO Amy Hood had already flagged during the company’s fiscal Q1 2026 earnings call, where she acknowledged Azure had been short on capacity due to surging AI demand across its portfolio — a shortfall she said likely capped cloud revenue growth. Amazon declined to confirm GitHub as a customer.
