Hello,

I'm using railway to serve up play-bolo.com - it's been running well enough for two months. it's a web game that runs at 50 ticks a second. after the infrastructure maintenance event on the 23rd the game is laggy and unplayable. I hadn't made any new deployments during this time.

On the 23rd I received this message in an email-

Hello,

Your Railway service will be affected by an infrastructure maintenance event.

• Resource: Project: focused-forgiveness / Service: web / Environment: production

• Duration: 5 minutes from time of this notification

• Impact: Reduced performance expected

There is no action required on your part. Normal performance will return once maintenance completes. We apologize for the inconvenience.

For questions or concerns, please contact us at station.railway.com.

Thank you for your patience,

What I have seen is unreliable message delivery.
Bursty Delivery Pattern:

Timing pattern: [0, 104, 2, 1, 1, 0, 11, 97, 0, 0, 1, 0, 9]

- Messages should arrive evenly every ~20ms

- Instead: 100ms gap → burst of 4 messages in 2ms → 97ms gap → burst

- This causes jittery movement and input lag

I suspect there's some buffering happening for WebSocket connections that wasn't present before?

thank you.
