Website Speed Test
Measure a site from every Pingniner monitoring location at once, broken down into DNS, connection, TLS handshake, server wait and transfer. One number tells you a site is slow; the breakdown tells you which part.
One measurement is a mood, not a trend
A site that answers in 200 ms today and 2 seconds next Tuesday looks fine every time you check it by hand. Pingniner records these same timings on every check and alerts you when the median moves.
