So I just wanted to share a quick anecdote and maybe save some headache for somebody else.

I recently set up an automation to check internet connectivity through cloudflare DNS, and if it’s down for a certain amount of time, powercycle my modem and check again.

My Internet kept going down on a consistent basis just about an hour ago, chalked it up to my ISP just being Cox. Finally investigated and figured out the problem.

You can probably guess where I’m going with this… Cloudflare DNS was down, my Internet was perfectly fine.

So now my automation checks 2 completely separate DNS before power cycling, and yours should too!
