0c213cbd-4233-4cb7-9ef1-615c05cfe365 You're free to look at the project and try to get the error: https://runnerspace.xevion.dev/ No specific page. Seems like an issue with kubernetes or whatever platform you're using to manage all the docker instances. Happens on mobile too. Just drops the connection. I think it's seizing up on the CSS too.

🚀 Cool. Didn't see any other reports yet so I was worried I was gonna have to start debugging a really old project 😭

looking into it We isolated the issue to resource exhaustion on some us-east proxies. We've retroactively created an incident with this context. Basically AWS SNS started hammering our proxies with a large number of connections solely in that region and it exhausted connections. We've shipped a mitigation, and also are adding more capacity to that region. Traffic ingested from other edges (us-west/europe/asia) were unaffected. https://railway.instatus.com/cln27mrdl75373bbofzz3mh17l
