I'm OK if e.g. Spotify is down, and it's unclear what to expect, but from a crucial business communication tool, no updates for 30 minutes is unacceptable :/
Reddit status page used to include graphs for errors and post/comment backlogs. Even if the overall status was not updated from green, it was clear that we're at the beginning of an incident based on spikes. It was too easy and useful, so of course they were removed.
Sadly, it's true for many products, but thankfully not all. How I interpret lagging status pages (I mean, this has been going on for 20+ minutes now) is that they are not capable of detecting outages, which really erodes my trust, especially in such a crucial tool. (I know that they do detect it in reality, I'm just stubborn :P)
