Ask HN: Can I check the connectivity of an ISP without being in its network?

You could follow a site such as https://downdetector.co.uk/ that aggregates reports of issues on sites including Vodafone.
Thanks. I should've mentioned that I want to do it myself, not relying on other services.
If you happen to know the address of a computer on their customer network (perhaps a router) you could check connectivity to that?
P.S. I don't want to use any third-party service such as Downdetector. I'm looking for a "technical" solution.
