How we know
Every 5 minutes our server in Germany sends a ping to a set of home and office routers inside O2 Czech Republic's network. A router counts only after it answered reliably for a day, and one router going quiet on its own (switched off, moved) is not an outage. When many of them stop answering at the same time, the network itself has a problem.
That shows large outages: a region, a city or the whole network. A problem in your street, with your own router or with one service is not always visible to us, which is why reports from people count too. Mobile networks hide most of their devices from the outside, so for those we rely more on reports.
