[Uptime] Sends lots of downtime messages

I'm getting multiple warnings from Uptime for my sites, today around 30-50 emails came. Can you help me fix the issue?

    Hello Will ,

    I checked Uptime for your site and it showed Socket Timeout error when the site was showing it's down. But this errors doesn't mean that site is down.
    There are some cases when the site is reported as being down while it's not really down, just slow. Our Uptime monitoring sets "limit" to 30 seconds so if the site doesn't respond with expected HTTP headers, it is considered as "down".

    Due to stability and performance (and results in reliability), we had to arbitrary set such "timeout threshold" so all these "connection timeouts" are reflected in the Uptime report.

    For example, a common reason that site might slow down is that in this very moment there is backup performed, so it was a temporary problem with a bigger load for the server.

    I could also see that your site experienced a 500 Internal Server error on 13th of June - this might be related to the Uptime reporting site down when in reality it's just responding slower to our pings.
    You can contact your hosting provider and ask what was an issue with the 500 internal server error and also you might try using Hummingbird and it's page cache and see if this will help with the problem.

    kind regards,
    Kasia

    I have had 500 emails since yesterday, it's seeming like it's just not worth using. None of my actual websites have gone down, so, my hosting company is doing their job. this number of emails is unmanageable

    Hi Will

    Sorry for the delay here.

    As my teammate reported on the first reply, we can see some 500 internal server error on Uptime monitor.

    I made a new Website Availability Test using Uptrend site https://www.uptrends.com/tools/uptime and you can see on some locations the site indeed is returning a time out and some other issues.

    I also can see the problem is intermittent, the list of location can change on tests.

    Some of the main issues are:

    HTTP Time Out
    Internal Server Error
    and 508 Loop

    You can learn more about 508 loops detected on.
    https://stackoverflow.com/questions/30529792/what-is-http-response-status-of-508

    As was told the Uptime will ping your sites and verify if they are available if not will send you an alert, it means that something is wrong with some location access and/or some performance and needs to be investigated.

    Please, firstly check with hosting provider for possible malware on hosting, redirect loops or any other problem server side, once you are getting the alert on different sites it can be the hosting instead of an application, however, in case host is fine, another troubleshoot test is a plugin/theme conflict.

    Remember, is important that you run a full backup first.

    Please deactivate all plug-ins, and check if the problem is gone you can use the https://www.uptrends.com/tools/uptime. If so, then enable all plugins one by one and find which one is creating the issue.

    If you still having this issue, could you do a theme test, much the same as the plugin test, but now you’re testing themes!
    Activate one of the default WordPress themes, like Twenty Seventeen or Twenty Twenty Nineteen.

    Let us know if you need any further help on this.
