June 2025 Summaries

Railway has launched an affiliate program offering a 15% commission on referrals' spending within their first 12 months, targeting creators of developer content such as YouTube tutorials, blogs, and courses. Participants can join by signing up for a free Railway account, obtaining a unique referral link, and sharing it through their content without needing prior approval. This initiative aims to engage the developer community by encouraging content creation that showcases Railway's capabilities, allowing creators to earn passive income from the tools they already recommend. The program is designed to benefit both Railway and its community by promoting more helpful content while providing creators with recurring revenue opportunities.

Railway experienced an outage on June 6th, 2025, affecting its GitHub Login and Backend API. The primary database faced imminent connection exhaustion, leading to request delays. Railway scaled rapidly, applying pressure to the database, which was not adequately prepared for the influx of users. When circuit breakers triggered, aggressive websocket reconnect logic overwhelmed the already stressed database, causing millions of requests to the backend. This led to a flood of traffic to GitHub's OAuth endpoints, triggering secondary rate limits on Railway's OAuth app. To mitigate the issue, Railway rolled out changes to reduce exponential backoff and implemented its own login OAuth rate limiting on top of GitHub's, gradually rolling out fixes within 24 hours. The incident highlighted the need for improved scaling, WAF configuration, and real-time logic to prevent similar issues in the future.
