⏱ Reading spike timing: a spike dates when users piled in — a lagging signal, usually days after an incident’s onset and often near its resolution (e.g. the Jun 2023 Libero outage began ~Jun 14; the questions spiked Jun 19). Treat these as pain-cluster / triage signals, not real-time incident detection.
🔎 Want a bump that is not listed below? The sparklines here are static text. Open the interactive explorer, pick a grain / version / cause, and click any point to read that period’s questions — every period, not just the ones that cleared a threshold. Each spike row also links straight to its own bucket.
🚨 Engineering signal — version × cause spikes
Cause clusters over-represented in a specific Thunderbird version. The Signal column flags 🆕 new (cause never spiked before), ↗ spreading (known cause, new version), or ↻ recurring (chronic / seen before) — ranked new→spreading→recurring, then by lift. Click an ID to read it.
📮 Cause-level spikes — provider / protocol / AV
Causes surging regardless of version vs a trailing month baseline — provider/ISP outages and protocol/AV issues. Not necessarily a Thunderbird bug, but worth a triage look. Ranked by magnitude.

Notes: spikes detected at monthly grain (coarser grains catch slow-burn incidents a daily threshold misses — e.g. the March 2026 GMX provider outage). Volume / cause / OS trends span the full scraper history (2023-01+). Version×cause covers 2026-02 onward — the native thunderbird_version field (Kitsune PR #7443) is only populated from Feb 2026 (~27% → 85% by mid-2026), so earlier questions carry no version; cause-level spikes use all history. Thresholds calibrated on the post-backfill baseline. Full IDs per spike in PROJECT1/desktop-monthly-version-cause-spikes.csv (version×cause) and PROJECT1/desktop-monthly-single-spikes.csv (cause-level); full series in PROJECT1/desktop-monthly-rollup.csv.
