<h1>About</h1>

<main>
<p>Этот dashboard показывает результаты регулярных HTTP-проб двух
speedtest-нод (FL — Финляндия, PL1 — Польша) от gitea-CI/CD-узла,
раз в 5 минут. Данные хранятся в SQLite на gitea-сервере и
публикуются как snapshot.json раз в 10 минут.</p>
<p>Цель — мониторить деградации latency/throughput для собственного
использования. API сервиса описан в
<a href="https://gitea.projectshitpost.fun/bergabruh/stats-gateway">stats-gateway</a>.</p>
