Sector observatories

One industry at a time, measured the same way: a fixed sample of real homepages, HTTP-observable signals only, scored transparently and published with the dataset and every exclusion named. 197 homepages across 7 published sectors. The speed test ranks any page against a wider corpus of 270, which also includes the verticals we have since retired — the measurements stand, so the data keeps working.
