Executive Summary​

Hashicorp's co-founder Mitchell Hashimoto decided to pull out his Ghostty project from GitHub in April 2026 due to GitHub's reliability issues. He did this after 18 years of using GitHub, saying that GitHub "is no longer a place for serious work".

GitHub has experienced a significant decline in reliability over the past 6 months, and Hashimoto is not alone in expressing this sentiment. In the past 12 months, GitHub has experienced 48 major outages, including outages in GitHub Actions, Copilot, Pull Requests, and core Git operations.

This article analyzes in depth GitHub's outage history between May 2025 and April 2026, the possible causes, and the impact on developers and businesses. IncidentHub has monitored every GitHub outage for the past 12 months and beyond - read on to find out what the data reveals.

Introduction​

Amazon Web Services remains one of the most popular cloud providers, with 200+ services in 39 regions across the world. Like all providers, they have their share of outages.

In 2025, IncidentHub detected 38 AWS outages, of which the one on October 20th had the most widespread impact affecting hundreds of SaaS providers simultaneously. Payments were disrupted, students lost access to classrooms, developer tooling degraded, and some IT teams experienced alerting gaps.

In this post we look at the reliability of AWS in 2025 based on their own publicly available status page data aggregated by IncidentHub, with a deeper analysis of the cascading impact of the October 20th outage.

Cloud Outages and Their Impact​

Cloud outages in 2025 ranged from minor ones affecting some sections of users, to major ones affecting hundreds or thousands of users. Services like Cloudflare and AWS on which many other services depend experienced outages that affected many due to the cascading effect.
