The task
The region needed a real picture of mobile connectivity: where the internet actually works and where coverage exists only on carriers' paper. Residents themselves had to collect it — without installing apps or registering.
What we did
We built a web service with a single GO button: it detects the carrier by IP, requests coordinates only at the moment of the check, measures ping, download, and upload in several parallel streams to the nearest Cloudflare node, and puts an anonymized point on the regional coverage map.
