Well if you're not providing a service to others, then you shouldn't be the ones to look into it. But if you're providing a service to users and they tell you it's down then you should. It might be that your ISP has a misconfigured route that is flapping and sometimes causes errors in some locations. Or a netmask is wrong somewhere and certain ip address can't be accessed. It might not be a temporary thing. And you if it's your ISP fault they might be able to fix it.

You've seem to think that you have to investigate the issues. On the contrary, you bump it up to your isp to investigate. If your ISP is regularly having these issues then it might be time to change ISPs to one with a better peering agreement.

If the outages were one of:

1. Reported as being experienced by an actual user of a web site,

2. Longer than a a couple of minutes at most (usually just a few seconds),

3. or happened more frequently than a few times per month,

then I might consider reporting it to my ISP. As it is, it’s not worth it. “Cosmic rays, man.” (https://www.joelonsoftware.com/2001/07/31/hard-assed-bug-fix...).
