Blackout Map can only show what it can measure. In some countries we have a handful of hosts to check, so a real outage is hard to see. If you know those networks, you can change that.

Apply for a probe Software probesA server that stays up and answers ping: an internet provider's DNS server, a university, an internet exchange or a public service.
Suggest a hostA provider's status page, a power company's outage map or a regulator's notices. They tell us what pings can't. Any country is welcome.
Suggest a sourceNo home routers, phones or anything else that belongs to one person. We remove what looks like one, straight away.
Nothing you were told to keep quiet about, and nothing you found by scanning.
They say little about the country's own networks. We need local providers, universities, exchanges and public services.
One address at a time, from your own knowledge. No copied lists and no lists from an AI tool: they are mostly dead hosts.
Suggestions can't make a country look up or down. Trying only gets the address refused.
A public address, in the right country, on a local network, and new to us.
We ping it every 30 minutes. It must answer 95% of the time.
Nothing goes further without our OK.
It runs alongside our hosts but doesn't count until it has proved itself. Even then, one host going dark alone is ignored.
