I think it all has to do with how companies react to their own outages and their processes around publishing the info. I imagine that bigger companies need to go through a process to validate all the information they share with the public.
I don't think it's a factor in how Statuspage works. Cloudflare, for example, uses them, and usually it's pretty fast to update their status page and release outage information.
For companies that need to monitor critical dependencies, my company ( https://isdown.app ) helps by aggregating status page information with crowdsourced reports. This way, companies can be alerted way sooner than when the status page is updated.
