HTTP-statuskoder efter klasse
Standardkoder linker til den RFC, der definerer dem. Koder, der kun bruges af Cloudflare eller nginx, er markeret som ikke-standard. Mærket på hver række viser, om en Uptimecheck HTTP-monitor tæller koden som oppe eller nede med standardindstillingerne (200–399 er oppe).

Tjek, hvad dit site returnerer
Det gratis website-tjek henter en hvilken som helst URL fra Stockholm og viser den statuskode, den svarer med, hver omdirigering på vejen, svartiden og hvornår certifikatet udløber.
Tjek et websiteHvilke koder skal en monitor alarmere på?
De statuskoder, der betyder noget for oppetid, hvilke der betyder reelle problemer, og hvordan du sætter tjek op, der ikke råber ulven kommer.
Læs snydearketSpørgsmål
Hvad betyder de fem klasser af statuskoder?
Det første ciffer angiver klassen: 1xx information (forespørgslen er i gang), 2xx succes, 3xx omdirigering, 4xx klientfejl (serveren afviser forespørgslen, som den blev sendt) og 5xx serverfejl. En klient, der ikke kender en kode, behandler den som x00-koden i dens klasse, så en ukendt 4xx håndteres som 400.
Hvilke statuskoder tæller Uptimecheck som nede?
Som standard tæller en HTTP-monitor 200–399 som oppe og alt andet som nede, og et nedbrud meldes først, når et andet tjek bekræfter det. Omdirigeringer følges, op til 10, og det endelige svar afgør det. Du kan angive de forventede statuskoder for hver monitor, for eksempel 200-299, 401. Det gratis Is it down?-værktøj tæller ethvert svar under 500 som, at sitet svarer.
Hvad er forskellen på 502, 503 og 504?
Alle tre kommer typisk fra en proxy eller load balancer foran applikationen. 502 Bad Gateway: serveren bagved gav et ugyldigt svar eller intet, ofte fordi den gik ned. 503 Service Unavailable: serveren er overbelastet eller under vedligeholdelse og siger det. 504 Gateway Timeout: serveren bagved svarede ikke i tide.
Er Cloudflares 52x-koder og nginx' 444 og 499 standard?
Nej. Cloudflare sender 520–526 for at beskrive problemer mellem sit netværk og origin-serveren, og nginx bruger 444 (luk forbindelsen uden at svare) og 499 (klienten afbrød) i sine egne logs. De står ikke i nogen RFC, så de er markeret som ikke-standard her.
