Microsoft is resorting to its biggest cloud rival to deal with GitHub AI capacity issues
Microsoft is temporarily using Amazon Web Services to handle GitHub’s surging AI-generated code demand after reliability issues strained its infrastructure. The move follows a spike in outages linked to AI coding tools, despite GitHub’s planned full migration to Azure. Sources confirm AWS capacity is being added as an immediate fix, not a long-term shift. GitHub’s May 2026 report showed nine service incidents, with weekly commits now at 275 million—up from 1 billion for all of 2025.
What changed

Microsoft turns to AWS to stabilize GitHub amid AI-driven outages
confidence 92%Microsoft is temporarily using Amazon Web Services to handle GitHub’s surging AI-generated code demand after reliability issues strained its infrastructure. The move follows a spike in outages linked to AI coding tools, despite GitHub’s planned full migration to Azure. Sources confirm AWS capacity is being added as an immediate fix, not a long-term shift. GitHub’s May 2026 report showed nine service incidents, with weekly commits now at 275 million—up from 1 billion for all of 2025.
What's confirmed:
- Microsoft is using AWS cloud capacity to support GitHub after AI-driven demand overwhelmed its infrastructure, triggering multiple outages.
- GitHub processed 275 million commits per week in April 2026, up from 1 billion for all of 2025, straining its systems.
- GitHub experienced nine service incidents in May 2026 alone, according to its availability report.
- The AWS capacity addition is described as an operational fix for immediate strain, not a strategic abandonment of Azure migration plans.
- GitHub’s COO confirmed the platform was on track for 14 billion commits in 2026 before the AI surge.
Still unconfirmed:
- Microsoft may reconsider its full Azure migration for GitHub due to ongoing reliability concerns (unconfirmed).
- The AWS partnership could signal a longer-term reliance on hybrid cloud setups for GitHub (not yet verified).
- Internal Microsoft documents suggest AI coding agents are responsible for 60% of recent GitHub traffic spikes (no independent confirmation).
