HTTP-statuskoder etter klasse
Standardkoder lenker til RFC-en som definerer dem. Koder som bare brukes av Cloudflare eller nginx, er merket som ikke-standard. Merket på hver rad viser om en HTTP-monitor i Uptimecheck regner koden som oppe eller nede med standardinnstillingene (200–399 er oppe).

Sjekk hva nettstedet ditt returnerer
Den gratis nettstedsjekken henter hvilken som helst URL fra Stockholm og viser statuskoden den svarer med, hver omdirigering på veien, responstiden og når sertifikatet utløper.
Sjekk et nettstedHvilke koder bør en monitor varsle om?
Statuskodene som betyr noe for oppetid, hvilke som betyr reelle problemer, og hvordan du setter opp sjekker som ikke roper ulv.
Les juksearketSpørsmål
Hva betyr de fem klassene av statuskoder?
Det første sifferet angir klassen: 1xx informasjon (forespørselen er underveis), 2xx vellykket, 3xx omdirigering, 4xx klientfeil (serveren avviser forespørselen slik den ble sendt) og 5xx serverfeil. En klient som ikke kjenner en kode, behandler den som x00-koden i klassen, så en ukjent 4xx håndteres som en 400.
Hvilke statuskoder regner Uptimecheck som nede?
Som standard regner en HTTP-monitor 200–399 som oppe og alt annet som nede, og et driftsavbrudd rapporteres først når en ny sjekk bekrefter det. Omdirigeringer følges, opptil 10, og det endelige svaret avgjør. Du kan angi forventede statuskoder for hver monitor, for eksempel 200-299, 401. Den gratis Is it down?-sjekkeren regner ethvert svar under 500 som at nettstedet svarer.
Hva er forskjellen på 502, 503 og 504?
Alle tre kommer vanligvis fra en proxy eller lastbalanserer foran applikasjonen. 502 Bad Gateway: serveren bak ga et ugyldig svar eller ingen, ofte fordi den krasjet. 503 Service Unavailable: serveren er overbelastet eller under vedlikehold og sier fra om det. 504 Gateway Timeout: serveren bak svarte ikke i tide.
Er Cloudflares 52x-koder og nginx’ 444 og 499 standard?
Nei. Cloudflare sender 520–526 for å beskrive problemer mellom nettverket sitt og opprinnelsesserveren, og nginx bruker 444 (lukk forbindelsen uten å svare) og 499 (klienten la på) i sine egne logger. De står ikke i noen RFC, så de er merket som ikke-standard her.
