5xx Server error
HTTP 508 Loop Detected
A WebDAV status: the server stopped because it found an infinite loop while processing a request that covers a whole folder tree. Some shared hosts also use 508 to say an account has reached its resource limits, a use outside the standard.
Defined in RFC 5842, section 7.2(opens in a new tab)
//_01 Uptime checks
Is 508 up or down for a monitor?
Uptimecheck HTTP monitor
Default settings
Down. It is outside the default 200–399 range, so a monitor reports an outage once a second check confirms it. If 508 is the answer you expect from that URL, add it to the monitor’s expected status codes.

Down. A 5xx means the server, or something in front of it, failed to answer.
//_02 Causes and fixes
Why you see 508 and what to do
Typical causes
- A WebDAV folder structure that loops back on itself.
- On shared hosting: too many processes or too much CPU or memory for the account.
If you run the site
- On shared hosting, check the account’s resource usage and what is causing it, such as bots or a slow plugin.
If you’re a visitor
- Try again later.
Know the moment your site stops answering as it should
An Uptimecheck monitor requests your page as often as every minute, checks the status code against the ones you expect, confirms a failure with a second check and then alerts you.

What does HTTP 508 mean?

Does an uptime monitor count 508 as down?
Down. It is outside the default 200–399 range, so a monitor reports an outage once a second check confirms it. If 508 is the answer you expect from that URL, add it to the monitor’s expected status codes.
Downtime is obsolete.
