Web Hosts #10 · 3 measurements · since Aug 21, 2026

The most recent attempt failed. PAGE_HUNG: Lighthouse was unable to reliably load the URL you requested because the page stopped responding.

Numbers below are from the last successful run, 28h old.

The measuring machine was slower than usual.

Lighthouse benchmark index was 1888.5 against a baseline of 2490 (-24.2%). CPU-bound metrics — TBT, TTI, main thread work — are affected by this and may have moved without the site changing at all.

What LCP is made of observed, unthrottled

A flat LCP number tells you something regressed. The subparts tell you whether it was the server, resource discovery, the download, or rendering.

Measured on the trace before throttling is modelled, so these are real durations that will not sum to the 6.67 s above — that figure is a simulation of the same load on a slow phone and connection. Read these for the proportions: which phase dominates.

element render delay 1.19 s

time to first byte 225 ms

Axe violations axe-core 4.13.0, full rule set

1 violating node across 1 rule, 1022 passing. This is a standalone axe run, stricter than the subset Lighthouse folds into its score above — and it is the second tiebreaker in the ranking.

moderate meta-viewport — Zooming and scaling must not be disabled 1 node

Accessibility failures 1 of 28 audits

Tracked as a count, not just the score — the weighted score is coarse enough that you can ship a broken component and barely move it.

meta-viewport — `[user-scalable="no"]` is used in the `<meta name="viewport">` element or the `[maximum-scale]` attribute is less than 5. 1 node
