What if your American cloud provider goes down? Why spreading the risk matters for your mailbox too
Why these outages have such a big impact
A handful of American hyperscalers carry a disproportionately large share of global internet traffic. That's efficient as long as everything works, but it also means one outage at one company can hit dozens of seemingly independent services at once, because they all run on the same underlying infrastructure without the end user ever knowing. Research firms like Forrester point out in their analyses for 2026 that a majority of European IT leaders want to lean more on local cloud providers precisely to break up that concentration.
What that means in practice for your mailbox
Say your business email, your accounting package, your CRM and your video calling all happen to run on the same hyperscaler. On a normal day you'd never notice. On the day something breaks, everything goes down at once, including the very channel you could have used to tell your colleagues, customers and suppliers what's going on. That's the real risk of concentration: not that one service fails, but that your backup channel happens to have the same problem.
If your mailbox runs with a provider that doesn't lean on that same infrastructure, email at least keeps working while everything else stumbles. No guarantee against every problem, but a way to stop one outage from leaving you completely unable to communicate.
Spreading risk isn't distrust, it's just good practice
Nobody finds it strange that you keep a backup of your files somewhere other than the original: that's basic IT hygiene, not distrust of your own server. The same principle applies to your choice of providers: it's not paranoid to avoid putting your mailbox, your backups and your core software all with the same company. It's simply spreading risk, the same way you would with any other critical part of your business.
And at Mailflux
Mailflux runs on its own European infrastructure, separate from the big American hyperscalers. That's no guarantee we'll never have an outage (no provider can honestly promise that), but it does mean a problem at AWS, Microsoft or Google won't automatically drag your mailbox down with it. Your mail stays on your own domain, hosted in Europe and GDPR-compliant, with automatic backups as an extra safety net.

FAQ
Frequently asked questions
So is Mailflux never down?
No provider can promise 100% uptime, and neither can we. What matters is that an outage at a big American hyperscaler doesn't automatically drag your mailbox down with it, because we don't run on that same shared infrastructure.
Do I need to spread all my cloud services across different providers now?
That depends on how critical each service is to you. Your business email is often your only communication channel if something else goes down, so spreading that risk is a simple, cheap precaution. Hunting down a separate provider for every single service usually isn't necessary or practical.
