Automated read of the latest data — bottom line, phase comparison, and notable trends.
Bottom line — Spectre_5 is healthy over the last 24 hours (response time mostly 480–700ms, apdex 0.76–0.85 outside one overnight blip) and stable across the past week (552–668ms, apdex 0.79–0.84, error rate under 0.6%). Early Drupal 10 (D10) numbers since Jul 4 are encouraging: 664ms average response and 0.38% error rate, both better than the Drupal 9 (D9) baseline (699ms, 0.42%) and roughly back to Drupal 8 (D8) levels (679ms, 0.39%), with apdex recovering to 0.79 from D9's 0.77.
A sharp overnight spike at 03:05 CDT pushed response time to 2346ms (vs a ~550–650ms norm) with apdex dropping to 0.44 and error rate rising to 1.39% — isolated to one low-traffic hour (936 requests) and fully recovered by the next reading.
Jul 25 was a notably quiet day (34.1K requests vs a ~140–150K weekday norm) and also the week's best-performing day: 552ms response and 0.84 apdex, consistent with load-sensitive latency.
D10's early read (six weeks of data) shows all three headline metrics — response time, apdex, error rate — improving versus D9, suggesting the PHP 8 upgrade pains seen in D9 are resolving under Drupal 10.
Weekly trend over the last ten weeks shows response time peaking at 747ms (week of Jul 7) then easing back to 617ms by Jul 21, with apdex holding steady at 0.76–0.79 throughout.
No sustained elevated error rates were observed outside the single 03:05 spike; day-to-day error rate stayed in a tight 0.12–0.57% band all week.

Method & caveats
Cutovers. Drupal 9 / PHP 8 went live May 23, 2026; Drupal 10 Jul 4, 2026 — marked on every chart that spans them.
Drupal 10 is an early read (~5 days). Its phase card uses the Jul 4–9 window directly.
Recent spike. Jul 8 shows an isolated response jump (≈2× the prior day), coinciding with elevated reports/progress-API latency that day — an operational blip, not a migration regression.
Source & retention. New Relic timeslice metrics (HttpDispatcher, Apdex, Errors/all), ~13-month retention — the full arc back to mid-2025 is covered. Percentiles (p95/p99) live in 8-day event data and are reported in the point-in-time reviews, not here.
