We have systematic CURLs run every 15 mins - 2 hours from this system and logging their status. Every other CURL for the past 2 months has succeeded except this. Is there a way to identify why this one failed?

This was a CURL result to my domain. This TCP-based traceroute was generated immediately following an error condition that we've recently detected.

Could anyone advise how we can look into the cause of this issue further? what might be the cause of the issue?

  • The output of curl would be helpful. Jan 26, 2022 at 14:41
  • Please also add tcptraceroute for a healthy connection. Most likely this is random internet connectivity breakage, which happens all the time. Jan 26, 2022 at 15:32

    The internet is not a guaranteed service. Only one failure in months is pretty good.
