History from the previous URL is included below, with the move on Sep 6, 2026. A step-change around that point is likely the change of address rather than a regression.
Lab data is measured using Lighthouse, Mobile mode unless otherwise specified. Field data is reported from Chrome UX Report (using p75 measurements).

Metrics LAB FIELD
Field figures are the p75 across real Chrome users over a 28-day trailing window (2026-08-22 → 2026-09-18), origin-level.

LCP Subparts LAB Unthrottled
The subparts attribute LCP to your server, resource discovery, download, or rendering. Note that the Lab LCP shown above is a simulated throttled estimate.
LCP LAB Simulated vs LCP FIELD
The lab LCP is 2.74× the field p75 — real users likely have above-average hardware or network connectivity.
