Deployments
The Deployments group answers one question from several angles: where is the network under-deployed? It is the group to reach for when you are making the case for a probe somewhere, or working out which gap to close first.
Most of it is staff-gated; the new-probes chart is public.
Country coverage
/deployments/country-coverage · staff
A live per-country rollup of the probe fleet — around 250 countries, returned in one call, with filtering and sorting done in the browser so it stays responsive.
Two lists carry the weight:
- Gaps — countries with no connected probe at all. Dark.
- Fragile — countries hanging on a single connected probe. One unplugged device from going dark.
The fragile list is the more actionable of the two: a country that has never had a probe is a long project, whereas a country one probe away from dark is something you can fix this month.
A condensed version of this — counts of dark and single-probe countries, plus recent transitions — appears on your dashboard, fed by an hourly detection pass.
AS population gaps
/deployments/as-gaps · staff
The same question at network rather than country granularity: which significant autonomous systems have no probes?
Two tabs over one filter set:
- ASN gaps — the per-AS table, the default landing view
- By country — a country rollup; clicking a row filters the ASN tab to it
The filters are what make it useful, and they are all reflected in the URL so a prioritised list is a shareable link:
| Filter | Default | What it does |
|---|---|---|
max_probes | 3 | Only ASes with at most this many probes |
min_population | 10,000 | Only ASes with at least this many estimated users |
country | — | Restrict to one country |
statuses | — | Which probe statuses count as "having a probe" |
The population figure is an estimate of users behind the AS, so the ranking is effectively users per probe — which is the number that makes the case for a deployment. Cross-check any individual candidate on its AS dossier.
The statuses filter deserves attention: an AS whose only probes are disconnected is arguably a gap, and whether you count it changes the list considerably.
Weather and outages
/weather · staff
No longer collected
Weather collection, the correlation report and the weather alerts were stopped on 4 October 2026: in their time they found nothing worth acting on. The page still shows everything they recorded, as it was left — nothing on it updates.
Correlates hourly per-country temperature against a per-country hourly disconnect signal derived from connection events.
The method is deliberately conservative, because both series have a strong daily cycle and a naive correlation between them would be spurious:
- Anomalies, not raw values. Each series has its hour-of-day mean subtracted before anything is correlated, so the shared daily rhythm cancels out.
- Lagged cross-correlation. Heat-related failures lag the peak — afternoon heat, evening load, power strain, probes drop — so the reported figure is the lag with the strongest correlation, not the same-hour one.
- Extreme-heat lift. The mean disconnect rate in the hottest 10% of hours divided by the overall mean: "when it's hot here, outages run N× baseline."
The page also carries the last per-country temperatures collected and the weather alerts that were raised.
WARNING
Correlation is not causation, and probe outages are a biased sample — they tell you about places with probes, on networks whose hosts leave them plugged in. Read everything here as a signal worth investigating, never as a claim about what happened.
New probes
/graphs/probes/new · public
Deployment rate over time: how many probes came online, filterable and viewable three ways.
- Chart — the default, and the one that carries a save-as-image control for slide decks
- Map — where the new probes are, loaded separately when you open the tab
- Details — the underlying rows
The tab is reflected in the URL, so a deep link lands where you meant. The filter panel starts open and collapses itself once the first result arrives, leaving the active filters visible as chips; after that it stays wherever you put it.
