Why do apps go down at the same time? The outage cascade, explained
You open Instagram and it won't refresh. You switch to WhatsApp — also broken. Then you notice your favorite game's login is failing too. It feels like the whole internet is having a bad day. Often, it is — and there's a specific reason why outages cluster like this.
Most apps run on a handful of companies
The apps you use don't each own a private internet. They rent it. A small number of cloud providers (Amazon's AWS, Google Cloud, Microsoft Azure) and content-delivery networks (Cloudflare, Fastly, Akamai) sit underneath an enormous share of the web. When one of them has an incident, every app built on it can wobble at the same moment — even apps from completely different companies that have nothing to do with each other.
That's why a single "AWS us-east-1" event can take down streaming services, social apps and games together, and why a Cloudflare problem can knock big sites offline in one sweep. The apps didn't fail independently; their shared foundation did.
Ownership cascades too
The other reason apps fail together is ownership. Instagram, Facebook, WhatsApp, Messenger and Threads are all Meta, sharing the same backend. When Meta has a bad day, the whole family goes down at once — as the world saw during the 2021 global outage. So if all of them are broken for you simultaneously, it's almost certainly Meta, not your Wi-Fi.
How to tell what's really happening
When several apps break together, the useful question isn't "is this one app down?" — it's "what do they have in common?" If the common thread is a cloud or a CDN, the outage is upstream, and there's nothing to do but wait it out. If only one app is affected, it's that app (or, occasionally, just your connection).
This is exactly what DownRN is built to show. Instead of only telling you that an app is down, it maps the cascade — what's likely going down with it, and which shared provider is the probable cause. You can see it live on the "is the internet down" view, or on any app's page under "what goes down with it."
The takeaway
Simultaneous outages aren't a conspiracy or a coincidence — they're the visible shape of how the modern internet is wired. A few providers carry a lot of weight, so when they stumble, everyone feels it at once. Knowing that turns a frustrating mystery ("why is everything broken?") into a quick, answerable question.
