Paris' subway and local train lines each have a Twitter account, and they are the only reliable source of information regarding outages. Phone apps (at least three official ones with different data sources!) and websites can be outdated. Displays in station too (though less often), have outages of their own, and (rarely) even incorrect updates.
It's been a while since I've used Twitter, but I thought the tweet ordering was never chronological. Has this changed? You just have to trust that the algorithm will always surface relevant information to the top of the feed?
Doesn't their own Île-de-France Mobilités app have reliable information on outages? Surely it's more reliable than their Twitter account?
Wow, this is kind of a mess, seems twitter won from usability standpoint here

It almost seems like we need laws that information about public services have to be available on a public website (as opposed to a third-party website that requires registration).
I personally do not know anyone in real life with a twitter account (although I have one, I have not used it in over 15 years), I wonder how many people just go without this information and are angry that it's (seemingly) not available.
