alt Hacker NewsSome hard numbers [1] as to why GitHub is struggling with stability issues, directly from GitHub's COO:
Yup, platform activity is surging. There were 1 billion commits in 2025. Now, it's 275 million per week, on pace for 14 billion this year if growth remains linear (spoiler: it won't.)
GitHub Actions has grown from 500M minutes/week in 2023 to 1B minutes/week in 2025, and now 2.1B minutes so far this week.
So we're pushing incredibly hard on more CPUs, scaling services, and strengthening GitHub’s core features.
All of which can be handled with horizontal scaling of identical components.
None of which explains poor latency when opening UI elements, which is more likely be explained by overuse of SPA or spaghetti code in microservices.
Update: yup, that’s exactly it, just as I guessed: https://news.ycombinator.com/item?id=47912867
