That's not how status pages if implemented correctly work. The real reason status pages aren't updated is SLAs. If you agree on a contract to have 99.99% uptime your status page better reflect that or it invalidates many contracts. This is why AWS also lies about it's uptime and status page.
These services rarely experience outages according their own figures but rather 'degraded performance' or some other language that talks around the issue rather than acknowledging it.
It's like when buying a house you need an independent surveyor not the one offered by the developer/seller to check for problems with foundations or rotting timber.
