What we measured
Only 2 of 3 passes could be measured (1 blocked). Figures are medians of the passes that worked.
During a 12-second window with no user interaction, the page made 10 requests to 5 third-party domains (median of 2 passes).
Of 2.3 MB transferred in that window (compressed responses that finished loading), 516 kB (22%) came from third-party domains, 316 kB of it from services classified as tracking (9 requests).

Comparison with last week
