Alternatively, get good at doing rolling releases so you don't take down the entire system and have some sort of canarying process.

- whycome 1y agoI think the rolling stock may be stationary right now. Updates relying on stationery.
- johnfn 1y agoI feel like some BARTs moving and some stuck might be a bit of a worse problem.
- ShakataGaNai 1y agoTrain rolling jokes aside, that makes sense... until it doesn't work. A traffic control system, the thing that makes sure all trains are in known locations, safely spaced, etc.... might be necessarily centralized. There isn't really a "rolling release" you can do for a single system. Should they have a separate test system for release before "production", sure. Do they? No idea. Is it identical to production? Clearly not. How does the saying go.... > Everybody has a testing environment. Some people are lucky enough enough to have a totally separate environment to run production.
