Host status is the availability indicator at the top of GSC's Statistiques d’exploration report — a historical record of ce que Google observed, pas a live uptime vérifier. It checks three choses — robots.txt fetching, DNS resolution, and server connectivity — over the dernier 90 days. Green signifie aucun significant problèmes; yellow signifie a problem happened plus que a week ago (it typically ages out of the report on its propre); red signifie un happened in the dernier week. The highest-stakes échec is an unreachable robots.txt: Google arrête exploration pour ~12 hours, alors falls back to the dernier bon mis en cache copy — si un exists — pour up to ~30 days, après qui behavior dépend on votre site's broader availability. It's the underlying robots.txt, DNS, or server échec que throttles exploration of the whole site, pas the host-status étiquette itself, and the state aging back to green isn't proof exploration, indexation, or rankings have entièrement recovered.

TL;DR — Host status is the availability lens at the top of GSC’s Explorer Stats report — a historical record of ce que Google observed, pas a live uptime vérifier — assessed over the dernier 90 days à travers three checks: robots.txt fetching, DNS resolution, and server connectivity. Green = aucun significant problèmes; yellow = an problème plus que a week ago (typically ages out of the report on its propre); red = an problème in the dernier week. The highest-stakes échec is an unreachable robots.txt: Google arrête exploration pour the premier 12 hours, alors falls back to the dernier bon mis en cache copy — si un exists — pour up to ~30 days, après qui behavior dépend on votre site’s broader availability. A 4xx robots.txt is fine (Google crawls freely); a 5xx/timeout/DNS échec is ce que pauses exploration — que underlying échec, pas the host-status étiquette, is ce que throttles exploration. There’s aucun reset button, and the state returning to green isn’t proof exploration, indexation, or rankings have entièrement recovered.

Ce que host status en réalité measures

Search Console documents host status dans Statistiques d’exploration and evaluates availability over the previous 90 days. Evidence for this claim Search Console Host status summarizes robots.txt availability, DNS resolution, and server connectivity over the previous 90 days. Scope: Google Search Console report terminology and documented Search behavior; the label alone may not prove the underlying root cause. Confidence: high · Verified: Google: Crawl Stats report Diagnose individual URL outcomes separately in Inspection d’URL or Page Indexation. Evidence for this claim Host status is a host-level Crawl Stats diagnostic rather than a per-URL Page Indexing decision. Scope: Google Search Console report terminology and documented Search behavior; the label alone may not prove the underlying root cause. Confidence: high · Verified: Google: Crawl Stats report

Host status réponses a narrow question: over the dernier 90 days, pourrait Googlebot reach the host at tout? That’s a différent question from “is this page indexed” or “does this URL throw an error.” It’s site/host-level availability, pas per-URL explorer errors — qui is exactly pourquoi I garder it mentally separate from Page Indexation.

It’s aussi worth being precise à propos de ce que kind of “availability” ce is. Host status is a historical record of ce que Google observed during exploration, pas a live uptime monitor — a green state correct now doesn’t prove votre site is reachable ce second, and a red state doesn’t prove it’s bas now, seulement que a significant problème crossed Google’s threshold sometime in the dernier week. Pour a live vérifier of the current moment, vous besoin a direct probe, pas ce report.

It lives at the top of the Statistiques d’exploration report (Settings → Statistiques d’exploration), qui is seulement disponible pour domain or root-level property accès — pas URL-prefix subfolders. The broader Statistiques d’exploration report covers volume and performances (total explorer requêtes, download size, average réponse temps, explorer objectif, fichier type, réponse codes); host status is the tighter availability slice. Quand I’m diagnosing a explorer slump, host status indique me si Google pourrait connecter; the rest of the report and my server logs tell me ce que happened.

The three checks

Google assesses host availability à travers three categories, chaque with its propre failure-rate graph in the host details:

  • robots.txt fetching“The graph montre the échec rate pour robots.txt requêtes during a explorer.” Ce is the highest-stakes vérifier (plus ci-dessous).
  • DNS resolution“The graph montre quand votre DNS server didn’t recognize votre hostname or didn’t respond during exploration.”
  • Server connectivity“The graph montre quand votre serveur was unresponsive or did pas provide a complet réponse pour une URL during a explorer.” Think 5xx, timeouts, and truncated/partial réponses.

The three states

The indicator summarizes ceux checks over a rolling 90-day window:

  • Green“Google didn’t encounter quelconque significant explorer availability problèmes on votre site in the past 90 days—bon job!”
  • Yellow / “had problems in the past” — Google encountered au moins un significant crawl-availability problème in the dernier 90 days, but it occurred plus que a week ago. Ce state usually self-heals: une fois a week passes with aucun recurrence, it renvoie to green. Vous généralement don’t besoin to do anything au-delà confirming the causer is gone.
  • Red / “problems now” — Google encountered au moins un significant crawl-availability problème in the dernier week. Ce is the un to triage.

So the yellow/red split is really simplement a timing distinction: red = dans the dernier week (“right now”), yellow = précédent in the 90-day window (“in the past”). The exact color noms and icon étiquettes are interface details Google peut modifier; what’s durable is que recency-based meaning.

Chaque category seulement counts as a “significant” problème une fois its échec rate crosses a threshold Google draws as a dotted line on que category’s graph. Google donne DNS échecs ci-dessus 5% of a day’s requêtes as un exemple of où que line sits — it’s an illustration pour DNS, pas a documented universal threshold que s’applique the même façon to robots.txt fetching and server connectivity.

Pourquoi robots.txt échecs are the la plupart dangerous

Si Google can’t obtenir an acceptable robots.txt réponse, “Google va slow or arrêter exploration votre site jusqu’à it peut obtenir an acceptable robots.txt réponse.” That’s a whole-site pause, pas a one-URL problem — qui is ce que rend a red host status driven by robots.txt an emergency.

The detailed timeline lives in Google’s robots.txt spec. Quand robots.txt renvoie 5xx, server errors, or network échecs:

  • Premier 12 hours: Google arrête exploration le site but garde trying to récupérer the robots.txt fichier.
  • Suivant ~30 days: si Google can’t récupérer a nouveau version, it falls back to the dernier bon mis en cache version pendant que encore trying to récupérer a fresh un. A 503 in particulier triggers fairly frequent retrying; si there’s aucun mis en cache version disponible, Google assumes là are aucun explorer restrictions.
  • Après 30 days: behavior diverges fondé on overall site health. Si le site généralement sert fine, Google behaves as si there’s aucun robots.txt (and garde checking); si le site has broader availability problems, Google arrête exploration le site pendant que encore periodically requesting robots.txt.

The critical nuance — and a courant myth — is the 4xx vs 5xx distinction. Google’s HTTP status-code handling pour robots.txt:

  • 2xx (success): robots d’exploration traiter the robots.txt as served.
  • 3xx (redirection): Google follows au moins five redirection hops, alors treats it as a 404.
  • 4xx (except 429): treated as si a valid robots.txt doesn’t exist — i.e. Google crawls freely.
  • 5xx / 429 / network / DNS: treated as server errors → the crawl-pause timeline ci-dessus.

So a manquant robots.txt (a clean 404) fait pas pause exploration. An unreachable un (5xx, timeout, DNS échec) fait. And critically, “a robots.txt fichier qui ne peut pas be récupéré due to DNS or networking problèmes, tel as timeouts, invalid réponses, reset or interrupted connections, and HTTP chunking errors, is treated as a server error.” A flaky DNS provider peut stall votre explorer exactly comme a 5xx.

DNS and server connectivity

DNS and server-connectivity échecs are plus intuitive but aucun moins réel. DNS resolution échecs mean Google’s resolvers couldn’t turn votre hostname into an adresse at some point in the window. Treat the spécifique causer as a hypothesis to confirmer, pas a donné — candidates inclure bad nameservers, an outage at votre DNS provider, or DNS-level rate limiting of Googlebot, and telling les apart nécessite votre DNS records, nameserver logs, and provider status history alongside the Statistiques d’exploration graph. Server-connectivity échecs are 5xx, 429, timeouts, and partial/truncated réponses; likewise, an overloaded origin and a CDN/WAF throttling Googlebot’s IP ranges are les deux plausible explanations que votre origin and edge logs — pas the graph alone — have to confirmer.

Ce ties straight back to fréquence d’exploration. As I’ve written in my budget d’exploration guide, “Google va slow bas leur exploration si ils recevoir aussi nombreux 5xx (server errors) or 429 (aussi nombreux requêtes) Code d’état HTTPs.” John Mueller made the même point à propos de how fast the explorer reacts:

“I’d seulement expect the fréquence d’exploration to react que quickly si ils were returning 429 / 500 / 503 / timeouts, so I’d double-check ce que en réalité happened (404s are généralement fine & une fois découvert, Googlebot va retry les anyway).” — John Mueller, Google.

There’s a subtle trap ici. Returning 503/429 is the legitimate short-term façon to tell Googlebot to slow bas — but it’s the même signal que drives a red host status. It’s a temporary throttle, pas a strategy: lean on it aussi long and vous risk pages dropping out of the index. The signal que lets vous ease a explorer is the signal que, sustained, semble comme an outage.

Ce que vous don’t besoin to do

A few choses personnes overthink:

  • There’s aucun “reset crawl rate” button. Fréquence d’exploration typically recovers on its propre une fois availability is restored — Google doesn’t document a fixed recovery window or SLA pour que, so don’t expect it to se produire on quelconque particulier schedule. The old manual crawl-rate limiter in Search Console was deprecated; vous don’t (and can’t) manually kick exploration back up.
  • Yellow usually fades on its propre. Une fois a week passes sans the problème recurring, the state ages back to green. Confirmer the root causer is gone, alors vérifier recovery independently plutôt que trusting the color alone: vérifier current reachability, watch the failing category’s graph trend back sous its threshold, confirmer explorer volume in the rest of Statistiques d’exploration semble normal à nouveau, and, si it matters pour a spécifique URL, vérifier recrawl/index status in Page Indexation.
  • It’s pas a ranking penalty. Host status affecte exploration, pas rankings directement, and on its propre it doesn’t expliquer a trafic modifier — correlate the affected window with explorer, index, and performances données avant assuming causer. The indirect risk is que a sustained inability to explorer eventually affecte freshness and, downstream, indexation — but there’s aucun manual action attached to a yellow or red indicator.

Host status vs the broader Statistiques d’exploration report

Garder the scopes straight. Host status is un section of the Statistiques d’exploration report — the availability lens. The rest of the report (the partie la plupart personnes mean quand ils dire “Crawl Stats”) is à propos de volume and performances over temps. As I’ve said elsewhere, quand you’re chasing a exploration problem “the meilleur placer to regarder is the Statistiques d’exploration report dans la recherche Google Console” — and host status is the premier chose in it I vérifier, parce que si Google can’t reach the host, nothing sinon in the report matters yet. The broader report is its propre topic; ce un is tightly à propos de the availability indicator.
