Is this a joke? Because that seems like exactly the wrong thing, and such a system would itself be a bottleneck for downtime issues.
Using twitter has the huge advantage that spikes in users in Spain for checking this stuff is a rounding error in the normal traffic so is very unlikely to take down the status page.
no one would/should prevent companies from using also private channels like X, FB, Instagram, etc but enforcing a public channel that doesn't require private citizens to register, accept T&S and share their private data with 3rd party, unrelated private corporations to be informed of critical, public safety information would be helpful.
