Services that would fail together with 1und1.de
These services share hosting, CDN or DNS with 1und1.de. A provider outage hits all of them at once, so if several of them are down too, the provider is the likely cause.
How we check 1und1.de
Is this 1und1.de's official status page?
No. It is an independent, outside-in view. Official status pages often confirm incidents late; we probe real service endpoints every five minutes and publish what we see.
When do you say 1und1.de is down?
A single failing request is reported as an error, never as an outage. A service is down after two consecutive failed sweeps, and we declare a provider incident only when several independent services that share the same provider fail together.
Why do other services appear here?
Because they share infrastructure with 1und1.de. When that infrastructure has problems, these are the services most likely to be affected next, even if their own status pages still say everything is fine.
