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

2 pointstheanonymousone3 comments

Suppose I want to check whether the Vodafone network in the UK is having an outage or not. I don't have a Vodafone UK subscription, and possibly I'm not even in the UK. Is it possible to check for outage still?

P.S. I don't want to use any third-party service such as Downdetector. I'm looking for a "technical" solution.

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?
