No. Status pages are communication tools, not technical instruments. Every provider filters through PR. AWS will never say "we broke everything" in the first hour. They say "increased error rates in region X."
The trustworthy source is your own monitoring. Everything else is narrative.
I worked with a provider who had an honest status page once. Small Canadian company. They listed every incident, no matter how minor. Went out of business in 18 months. Customers fled at the first yellow indicator.
This thread is depressing and accurate. The answer to OP's question is "there is no good answer, only adequate compromises."
My adequate compromise: UptimeRobot free, screenshots, email archive, credit card. Used it twice in 5 years. Worked once, failed once. 50% success rate. Better than nothing.
50% success rate is honest. Most "solutions" in this thread are untested confidence. "I do X, it should work." Have you actually disputed? Actually needed the documentation?
I needed it. Once. BuyVM, storage upgrade that didn't apply. Had screenshots, email, ticket history. Provider fixed it in 2 hours. Maybe they would have anyway? I'll never know.
The documentation made me feel prepared. That's worth something even if unused.
Feeling prepared has value. I sleep better knowing my documentation folder exists. Even if the dispute success rate is uncertain, the anxiety reduction is real.
Call it security theater if you want. Theater can be comforting.
In France, a "mise en demeure" (formal notice) costs nothing to send yourself and has legal weight. I've used it twice for consumer issues, never hosting specifically. Providers respond because ignoring it affects their legal position.
Estonia same. But as I said earlier, non-EU providers ignore it. RackNerd laughed at my "Estonian consumer protection" mention. Their exact words: "we operate under US law."
